Water in passenger footwell

[PaulP38a]

Noticed a small puddle of water in the (LH) passenger footwell the other day. It was a particularly hot day down here and I'd been doing a lot of driving. Reached my hand up under the glove box and the drops seemed to be coming from, or above, the air duct.

I'm suspicious that it is due to the A/C condensor but have no water on the RHS (lower duct removed). Stuck a stick up the "duck's bum" drains on each side of the transmission tunnel and no water came out.

As far as I know, my windscreen seal does not leak... we did have some rain a couple of days before this and I had recently taken it through a carwash.

found this similar thread http://www.aulro.com/afvb/discovery-1/48051-air-condtioner-leaves-water-passenger-footwell.html

Any other suggestions welcome.

Cheers, Paul.

must be contagious:eek:all started after I replaced the VC in the T/F case...had to manipulate the transmission on a jack after removing the mount...
Now when I remove the trans hump side panel and the panel under the glove box, the water ceases to drip on the floor into the LHS footwell ...put the side panel back and... more water in footwell
Am wondering if the side panel is crushing the drain tube... more experimentation ...driving back to Bris tomorrow from CBR...do I/don't I replace the panel...further report to come...

ps: so far 2,510km, actual fuel average 14.2 L/100km

cheers

The drain tube is a piece of convoluted rubber tubing that does not follow a straight path up to the air con drip tray.

Here are a couple if pix I took earlier:

Last time you got water in the passengers footwell it wasnt your aircon either:D

very funny :D
and true, but at least I knew where that water was coming from... it was the river half way up the doors

[PaulP38a]

Did a bit more investigation in to this problem today... after my daughter complained about water on her feet.

It is worth noting that the car has been not been directly exposed to rain for the past couple of weeks.

I popped out the glove box... GPS and iPod connect shown below
http://paulp38a.com/gallery/d/3159-1/IMG_1841.JPG

Took off the centre console side panel to expose the A/C drain
http://paulp38a.com/gallery/d/3161-1/IMG_1842.JPG

Attached a length of plastic hose and blew/sucked in both exposed drain points. Not much rubbish in there.

Removed the A/C ducting and found this puddle
http://paulp38a.com/gallery/d/3163-1/IMG_1843.JPG

I reckon the water is coming from the LHS blower motor.
http://paulp38a.com/gallery/d/3165-1/IMG_1844.JPG

So I decided to check the pollen filter. No real signs of water ingress here, so I'm still stumped.

Here's the funny thing:
I ran the A/C with the LHS duct disconnected and found the LHS blower motor was blowing outside air towards the centre... and the RHS motor was blowing cold air towards the LHS... so warm air from the outside would be hitting cold air from the centre/evap unit.... if year 10 science memory serves - this would lead to condensation.

Perhaps the problem is not actually condensor related, but the LHS blower pushing warm/moist air against cooled/de-humidified air?

I'm going to replace the mesh in the plenum anyway and check for blockages in drains... pics here Plenum Air (http://paulp38a.com/gallery/v/99RR/plenum_air/)

Cheers, Paul.

Nice work Paul (as always)

Looking at your pictures, I have a slightly unrelated question.

Can you access the left hand side recirc flap motors just by removing the glove box etc as you've done in that last picture ?

I need to get in there and have a look at mine, but I thought one had to move the entire dash to get to it - which put me off.

If I can get to it by removing the glove box it might be more do-able.

Thanks

Removed the A/C ducting and found this puddle

Good photos Paul and Ron. I've got the identical problem to you Paul, water in that ducting area and then onto the passenger footwell. My drains are clear and water runs/drips out of them just fine, but I still get water in my footwell. Mine seems to be appearing from around that lower ducting joint - right where your photo shows that small puddle. I'm mystified as to where its coming from. Being in Melbourne we've usually got pretty low humidity so I wouldn't of thought humid outside air hitting dry inside air would be enough to create such a relatively large amount of condensate, but it could still be it I guess. I've mostly noticed that water on the very hot days where I assume the aircon is working the hardest.

I replaced my pollen filters about a month ago, but have hardly taken the P38 out in the rain so I'm almost certain its not rain related.

[PaulP38a]

Hmm, maybe. It is pretty tight in there but depending on where the screws/bolts are it may be possible.

As it turns out my LHS recirc flap is stuffed too, so I guess I'm about to find out if it can be removed without pulling out the dash :o

Cheers, Paul.

Yep, exactly the same thing mate... same spot and all.

Wondering if my inoperable LHS recirc flap is contributing?

If you pop out your LHS pollen filter so you can see down to the blower, and set the HVAC to recirc, does your flap close?

Cheers, Paul.

Just went out and had a look. My recirc flap is working and the flap closed as it should.

paul, the p38 doesnt have a centre blower motor, just the one on each side.:confused:

Are you sure your 'duck bum' drain doesnt have a split on the concentina? i have seen this before when i have ripped them apart.

doh! of course it was the RHS blowing aginst the LHS. :o

No obvious splits that I can see.

Unfortunately, I haven't had much of a look at it today... been distracted by getting a certain web site relocated to a new host and all the "fun" associated with that ;)

I'm getting a leak in both footwells after rain and car wash - guessing this is most likely a windscreen seal issue? The seals do look old, just not sure which zebra i should be chasing first.

I had water dripping from the RH side & ended up stripping the intake system apart & resealing it all. It hasn't leaked since & last week's rain was a good test for it.

another doh! I forgot to send you money yesterday... doing it now :o

Hoping to get back to that water problem this weekend, after Andy and I visit the Queanbeyan 4WD Spectacular in the Hard Rangie with new go-fast stickers on it :D

[PaulP38a]

some progress to report...

Andy brought down another blower and recirc flap motor today. We pulled off the windscreen surrounds, air plenum panels and gave it all a good clean, getting lots of leaves and other "stuff" out of the drains.
http://paulp38a.com/gallery/d/3211-1/IMG_1866.JPG

While we had the plenum air intake panels out, I took the opportunity to replace the broken filter mesh with new "duck pond" filter mesh
http://paulp38a.com/gallery/d/3225-1/IMG_1873.JPG

Put it all back together and operated the recirc flaps. All good, both are working again.

Went for a run down to the Queanbeyan 4WD Show in the rain and mud. Came home and now I've got water dripping in to both footwells. The source definately seems to be the air intakes as both pollen filters are wet and you can feel the drips at the bottom of the flaps.

Tomorrow I'll take it all apart again and re-check the seals, and maybe put some silastic along the plenum panels.

Cheers Mike - it's all a fun learning experience. I got over my fear of tinkering with the car a long time ago, as you know and have helped me in the past ;)

As for the Holden Crewman AWD I bought recently, I'm pretty hesitant to touch anything on that yet :o

Yes - thanks, Andy told me to use the Sikaflex today too. If there's none left in the garage, it'll be a drive down to SCA or AutoPro in the morning...

I got a Pov Pack 4.0, no sunroof. I live in Queanbeyan, not Red Hill ;)

Cheers, Paul.

[Junosi]

I seem to have fixed mine at least temporarily. I've run a bead of silicon to act as a dam inside the outside edge of the duct with the puddle in it (haven't glued the ducts together). I'm hoping any water buildup will now be blocked by the dam and run down the duct and out the drain like it should.

Drove about 300k's yesterday (picking up new lpg tank) with aircon on the whole way and no sign of water when I got home. Don't know why the water is there in the first place still, puzzling ;) P38 hasn't been out in the rain for weeks/months now.

PM sent :angel::wasntme:

[Junosi]

Silicon dam hasn't worked, puddle in footwell once more =/ Have noticed that the foam stuff that seals both ends of the duct was very perished and allows a significant amout of air to blow by. Got me wondering about Paul's condensation theory again - as it seems to be the only plausible reason for water appearing there. Wondered if maybe the seals on the left hand side were ineffective while the right side was still fine - this might make the border where warm wet outside air hits cool dry aircon air occur further up the duct - thereby causing condensation. Might be grasping at straws here... :D Anyways I bought a new roll of foam seal stuff and resealed each end of the duct so that no air leaks out - time will tell if it still produces condensate.

[Hoges]

Condensate is pooling in the system somewhere...warm moist air is drawn in from both sides passes through the heat exchanger, moisture condenses out and drips into the collection tray and runs down each side of the transmission tunnel and out underneath...that's the theory. Need to carefully examine the condensation tray and blockages therefrom...

[Junosi]

Condensate is pooling in the system somewhere...

Yep but why its forming so far back up the duct is the mystery - its not the normal drain problem and there's no blockages as both drains are running freely =/ Paul's photo shows the puddle I'm talking about - quite high up yet that's where water is gathering. Pretty much has to be condensation but why its occurring way up there I just don't know.

[Hoges]

Some good stuff from one of our Sth African P38 confreres and who, it would appear, also earns his living fixing others' 'stuff-ups' ! Some very interesting examples of how not to do things!! RANGE ROVER WORLD (http://rangeroverworld.blogspot.com/)

It has some practical ideas including what to look for re water leaks, EAS problems...e.g. using an inline fuel filter as an air filter to stop dust getting into the air compressor intake etc etc

Hi Guys

I just found a small patch of water in the LHS pasenger footwell, and through to myself "I'm pretty sure I read something about this on AULRO".

Had a look underneath and could see water driping from the ducksbum under the dirvers side, but nothing on the passenger side.

Poked the ducks bum with a screwdriver and about 50ml of water landed on my face. Which was totally expected but how else can you see where to aim.

Fortunatly no need to go exploring behiond the dashboard yet.

Thanks to everyone who contributed.

Cheers
Rob

[PaulP38a]

update to my problem...
Went for a drive down the coast on Saturday to take the "puppy" for her first trip to the beach... as you can see from the pic below, she hated it and wanted to rescue every bit of seaweed should could find :D
http://paulp38a.com/gallery/d/3375-1/IMG_0288.JPG

It was approx 30degC and the A/C was on pretty much all of the time until SWMBO complained that it was too cold on the way home. When we got home there was a sizeable puddle of condensate in the passenger footwell and water dripping out of the passenger side drain point.

Sunday I decided to take it all apart again to fix the leaking bits from the rain and try to trace the condensate leak.

Lost the plastic end of my flexi-tool up the LHS drain plug... called Andy who told me where to drill a hole to recover it... 1" hole about here allowed me to extract the lost bit and a 1" bung plug from SCA to fill it.
http://paulp38a.com/gallery/d/3273-1/IMG_1920.JPG

replaced the perished foam in the ducts with weather strip from the hardware store
http://paulp38a.com/gallery/d/3269-1/IMG_1918.JPG

wherever there was a chance of water entering through the plenum, Sikaflex was applied

rejoined the duct and made a better seal using duct tape

More heat and rain this week... the journey continues.

Lots more photos of this project at Plenum Air (http://paulp38a.com/gallery/v/99RR/plenum_air/) just haven't documented them yet.


Cheers, Paul.

[Junosi]

People acutally use duct tape for ducting ? /gasp That's a first :D I should of done that bit too in hindsight - although just replacing the seal seems to be doing the trick so far with no condensate for a couple weeks now

[DT-P38]

Now all you gotta do is teach that pup/dog to steam rice and slice tuna... and then you can open the first ever Mr P38a guru sushi bar! :p:p:p

You should nick-name the thing NORI! :D:D:D

You should nick-name the thing NORI! :D:D:D

LOL - we got to smell the NORI all the way home in the car too, and it lingers there still :D

Her name is Lilly. Close to Nori but of the pond variety :)

[PaulP38a]

It has been a couple of weeks since I pulled it all apart and Sikaflexed it all up again.

During that period, the Rangie has driven through torrential rain, sat overnight in said rain, driven on hot days with A/C blowing and has not shown any signs of water/condensate leakage through the ducts or the blowers.

Not saying that it is fixed... just that it is all good so far. Where's that bit of wood to knock on?

Cheers, Paul.

[Junosi]

I reckon mine is cured too - since I replaced the foam sealer around the duct joints I haven't seen any sign of 'drips' or the usual puddle on passenger floor. Still don't know why it was happening - but fairly sure it was due to the perished duct seals leaking so much air (and then condensate)

[DT-P38]

Funny, Mrs 100 series has this issue too! Doesn't happen all the time, and have cleaned the drain pipe once which appears to (inconsistently) fix it!

[PaulP38a]

One of the A/C units in my house has a habit of dribbling condensate on my wine rack occassionally :o

Short term fix is to blow-back through the drain line to unclog whatever rubbish or insects have lodged themselves up there.

So, not a P38A problem perhaps? and one shared with Toyos and Fujitsus.

Still no sign of water on the floor of the P38A yet, but will see how it goes on the 4WD outing this coming weekend.

Cheers, Paul.

Hi all
Having just purchased a 2001 P38 the first problem is exactly what has been described here, AC condensate is leaking from the join in the duct work on the LH side.

https://www.aulro.com/afvb/images/imported/2012/02/1187.jpg

The carpets are quite wet and water is dripping from a join in the bodywork near the rear edge of the passenger door

Car hasn't been in the rain or been washed recently but the AC has been operated quite a bit. Does seem strange that the water leaks so far up the duct work rather than on and around the evaporator, Have checked the 2 drain tubes which were clear.

Has anyone been able to find a cause for this problem and made a suitable repair?

[Hoges]

Read above posts...

Re. the duct from the LH blower to A/C plenum: it needs to be sealed up. To do this, remove the glove box entirely as well as the transmission side panel. Good description in RAVE plus there's an excellent collection of relevant photographs both on this forum and Range Rovers (http://www.rangerovers.net) under "Common Problems and Fixes" in the 4.0/4.6 section.

UPDATE WATER IN FOOTWELL -POLLEN FILTER PLENUM
sorry about the photos... not sure how to get them in place other than thumbnails...

Having removed/resealed/replaced pollen covers several times without stopping the leak, decided to dig deeper. Removed glovebox etc etc water dripping from bottom of the LH blower housing.
Removed windscreen wipers and windscreen plenum cover/mesh etc then on a hunch removed the steel cover from the pollen filter housing. This is what I saw:

Vehicle has been parked in torrential Bris rain for past 12 days...not a drop in the footwell..

[wild_willy]

^Thanks Hoges
Great find and some nice pics of the culprit. Well done.
I am not sure that this is the cause of my wetness though as it hasn't rained in Melb for a while but sure has been humid. Did the water in your case leak from the join of the duct to the blower casing?

There was a lot of water from the LH AC drain as well as water leaking onto the carpet from the duct join but I guess it may be possible that water from washing the car could remain in the lower duct and with the humid weather using AC it might just cause an overflow at the duct join.
I will need to investigate this further and will certainly look at the possibility of water getting in as in your case.
Strange beasties these!

[Hoges]

G'day wild-willy.. I surmised clean water in the footwell (not coolant!!) came from possibly two sources... the pollen filter plenum...now fixed I hope! and condensate from the aircon.

As best I can determine, the large duct transfers air from the blower to the aircon condensor so I'm at a bit of a loss to understand why the condensate would form in that duct...

I haven't tested the aircon yet in this humid weather to determine where the condensate is coming from. It may be a loose duct connection situated above the large one, i.e. that which carries cold air from the condensor to the middle and side vents...

I've checked the connection of the condensor drain to the transmission tunnel drain...seems OK...

Now I need to test the aircon... will let you know

ps how did you get your photo to come up on the page without a having to resort to a thumbnail!!?

[wild_willy]

Hi Hoges
Yes clean water - you could drink it at a pinch. I haven't really had a good go at this yet as I've only had the car a few days. I pulled the panel off below the glove box to find where it was coming from and found that the foam at the duct join was soaking wet, Seems like others have had a similar problem (see earlier in this thread). I am wondering if the ducting can be fitted poorly (at the wrong angle???) which then allows condensate from the AC to run back instead of out the intended drain. Need to look further. Will let you know what I find.

I use Photobucket to upload my pics. Then just copy and paste the IMG code from there and into here. Once you upload the pic just click on the IMG code box and it will automatically copy for you.

since undertaking the following "repair"...

https://www.aulro.com/afvb/images/imported/2012/02/222.jpg

Rangie has been sitting out through a series of tropical rain "events" for past 3 weeks (think 'deluge') ...not a drop of water on the rubber floor mat...can't say same for spare wheel well but that's a different story!

cheers

[DaveKelly]

Paul - I took all the ducting out of my P38 recently and when refitting had all sorts of trouble trying to get the LH fan ducting back up and aligned under that pollen filter. In the end I did a temp fix with duct tape. HAD TO - NEEDED CAR BACK ON ROAD. Any case - just a thought as it appears this join could be an easy route for water entry.
Now its back into the Disco and finish the Cam Belt.
Cheers

[PaulP38a]

You are quite right I think Dave. The duct tape on my fix is the most likely source of the leak (if/when it occurs again), and the perishing foam seals where the duct joins at each end.
Another "roundtuit" job.

Cheers, Paul.

[Hoges]

Seal first with a thin line of duct tape for mechanical strength then overlay with 25mm wide "rescue tape" ...amazing stuff!...excellent!

rain or aircon?...or both?

[Craig_Keira]

Hard to know. Coming in over the OBD port. Definitely not coolant. It's been raining for days here. I'm going with rain until proved otherwise. Also, the aircon condensation does appear to be coming out under the car. It would appear that isn't blocked (not impossible!)

[zhoey]

I have been reading the threads with interest.

My RR is used under tropical & really humid conditions and I rarely have a problem with condensation, irrespective of whether I run the aircon in fresh air or re-circulation mode. I have had 2 previous experiences where I had condensate in the passenger footwell:

1) Condensation is due to icing of the evaporator coil.

2) Inadequate insulation of the aircon pipes running into the vehicle cabin.

This are my only experiences of having condensation leak back into the passenger footwell.

I would take a look at the wiper arm spindles as a suspicious leak point as well.

Must be an "age"thing...:( I thought I'd posted a reply...

For Rain:
check post#45 on this thread ... odds on it's the plate covering the pollen filter housing.

The water collects in the bottom of the LH blower, drips on to the tray behind the glove box and pools there until it overflows through the OBDII port...

To seal it will require you to remove the plenum grating in front of the windscreen (and w/s/wipers) plus the two side plastic plates.
The metal cover is held by 5 hex screws (10mm head). Remove it and seal it as per the photo. While you have the grating off, check the state of the filter mesh below. If you need more, you can get it from CLarke rubber (duck pond filter material). The whole job should take about 2 hrs incl cup of coffee time!


If it's the aircon, water pools in the same place and also drips through the OBDII port. That requires sealing the ducting (from the blower to the heater box) where it connects with the heater box... that's a bit more tricky...

I do believe i have a fix...am in the middle of experimenting...will post ...with pics now I finally understand how to do said magic!

Do you have a copy of RAVE? try and get one if you don't...it's invaluable

good luck

A METHOD FOR STOPPING AIRCON CONDENSATION LEAK
After 13 yrs the duct seals appear to be "shot", allowing condensation from the aircon to drip into the footwell rather than be "pushed" by the airflow into the proper place for drainage via the hole in the transmission tunnel...

One reason for this may well be a stuck mixing chamber flap which seems to operate effectively only when the ambient temp is below 15degC and the HEVAC cycles on start up. when the external temp is above 15 degC ...the book symbol appears and one gets cold air all the time in the passenger side... methinks it needs the 'self-tapping-screw-in-the-heater-box'fix...

to the task at hand:

Removed the panel behind the glove box, and then the glovebox.

With a bit of fiddling, removed the duct between the LH blower and heater airbox.

Cut the duct twice and removed a section so that each end could be re-attached without diisturbing the other...this is important.

Cleaned the external surfaces of blower connection and airbox connection to remove residual decayed foam.

after cleaning internal surface of connecting section of each end, pressed in single sided adhesive sealing material (Clarke Rubber) 25mmx 5mm. Experimented with various thicknesses: the 5mm thick material provides a "precision" fit

then added a generous bead of neutral cure water-based colorbond sealant at the inner extremity of travel of the "inner sleeve" where the two sections slide together. This provides a seal with out necessarily gluing the sliding sections together

https://www.aulro.com/afvb/images/imported/2012/02/4.jpg

Refitted each end.

https://www.aulro.com/afvb/images/imported/2012/02/5.jpg

Then insert "missing link" and seal with duct tape
https://www.aulro.com/afvb/images/imported/2012/02/6.jpg

Let sit for 12 hrs for sealant to cure then start aircon...

Very humid day...no more wet feet :banana::arms::clap2:

The automotive airconditioning people over here have some kind of a "memory" foam strip that can be used. Dunno if they have the same thing in Oz.

Stick it to the inner surface of the duct like you have done, compress the foam strip, then assemble the ducts. The foam over a few minutes, expands and fills whatever gap there is.

Had a water "problem" in my Discovery front carpets recently, turns out the new windscreen (fitted by dealers panel shop), was probably not heat sealed into place well enough.
I could actually get it to lift in places when I tried.
Found that problem, by getting somebody inside to watch while I ran a hose around the outside edge of window.
The fitter for my next winscreen will probably NOT be impressed; but I Just used mastic screen sealer around entire edge and water on floor stopped happening.

I've just (I hope) fixed my issue with LHS footwell water. Got under to clean out the drains. LHS side had a bit of gunk. But the RHS had a lot of gunk. Perhaps there is a common point under the dash that allows water to go from one to the other? In which case, perhaps cleaning out the RHS fixed the water on the LHS. I shall report back later.

"That" time of year again... several days of non-stop, often teeming, rain. This time, 12 months on, not a hint of water in either footwell nor in the wheel well.:banana: :banana:

What's more, with the reduction in ambient temp and a couple of judicious squirts of silicone spray into one of the HEVAC plenums, the flap is now sliding to full extent and the book symbol has gone (for a rest I suppose!):D

Hasn't prevented water seeping in through the colourbond roof on the house however due to deterioration of a couple of sealing washers on the roofing screws:mad: ... life goes on

I had my whole ceiling replaced 2yrs ago because of that! God bless insurance! Would have cost me 3 P38's to do it myself... The sad part is that when the ceiling gave way, it ended up landing on my Rangie...

Now my turn but only when aircon on so hopefully just a blocked or dislodged drain. Hello strangers :)

G'day Remy ! it's been a while!;)
I poked and prodded the Passenger side aircon drain pipes...all clear...was still leaking. I finally discovered after 2 yrs of frustration that while the pipe was clear, and it would squirt when squeezed, the "fingers" on the end of the pipe were actually sticking together sufficiently to overcome the weight of water above them...so it just backed up and dripped cold water on SWMBO's dainty feet:twisted: she started to develop a complex about it:eek: Anyway I finally snipped a couple of mm from the end of the pipe.:angel: Humid summer in Bris is now quite bearable without the complimentary footwash!
Trust all is well down Wagga way!
cheers

Remy!! Haven't seen you in a year... literally it was about a year ago we were in WW to collect my fur-baby.
Got another bit off your car today to go on my black one... should make it sound nice... you know the bit ;)

Back to the thread... knock on cellulose/lignin, neither of my P38's have started dripping condensation in the LH footwell this summer. If they do, Hoges... you are da man!

You might be better off posting this in the Range Rover Sport L320 group? Do you have a sunroof in your L320? The drain tubes are prone to perish and let water into the cabin. If it is this expect your key fob to no longer unlock your doors in the not too distant future....fortunately there are relatively simple and cheap fixes.
