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

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.



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?

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 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:

Note water drops under top edge of cover outline, dark stain on filter indicating water..

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

^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!

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!!?

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.

I did the same thing a couple of years ago. See post 17 in this thread.
