AC Drain

[davidgate]

Seem to have a blocked AC drain - a bit of water in each footwell. It's not rain as it hasn't rained in Brisbane for some time.
Can anyone advise where to look and how to get at it?

Thanks

Is yours a TD5 or Puma?
TD5 it is directly behind the lower shroud for the fan. The shroud will need to come off if you want to access the t piece. The usual culprit is the hose pulls off the t piece. I cable tied mine back on yesterday.
You may need to push the hose back through from the wheel arch area depending on where it is routed. They usually have an elbow on them as well.
If it is actually blocked you can use some thick wire to unblock from underneath.
You cannot miss the drain tube hanging down.

CraigE - mines a Puma. Had a look round but can't see anything obvious.


Thanks

Hi All
I know of a similar problem that is being caused by the thermostat that controls the AC compressor run time. The compressor keeps running which makes the system freeze up, then the drain system can`t keep up with the amount of condensate water being produced, or is missing the drain system altogether.


You should still have water flow from the drain, if not go for blockage.
Other symptom's, you may find inside temperature a bit cool/cold and not be able to adjust, then get a bit uncomfortable/warm.
The fix, are you still in warranty? :) SEE your dealer and ask for the ac compressor/thermostat be checked. Do not except blocked drain if problem persists and there is flow from drain.
I have been told the thermostat will cost about $90.00 and TEN ( 10 ) HOURS !! to fit/repair. This is with Puma model Land Rovers.

piece of whipper snipper string up the drain pipes does wonders when you figure out where they go.

Finding the drain is the hard part!

If it helps your search, when my Puma is parked slightly uphill the AC drain runs down over the gearbox.

I've been running the AC a bit lately I'll have a look under next time it's dripping and see if I can locate.

I've worked out so far it drains from the evaporator coil which is directly over the gearbox - can't see it directly so I'll be buying an inspection mirror today.

I found it! And got a face full of water.


For reference, the drain is a rubber pinch valve located about 150mm back from where the transmission tunnel starts.


Mine was just gummed up and cleared readily.

Found it just above the transmission. Little square pinch valve. Gave it a few milks and some water dropped out. Would not care to put a trace up there with line. Pretty awkward to get to .... Will see how goes...

Were some of you saying yours drips inside the vehicle? That doesn't sound right. Mine stays outside

If the drain blocks up, it overflows into the footwell.

Just got my aircon sorted on my 300tdi defender (stopped working last summer)
Works a treat now, but after a while it looses effectiveness and sounds like water sloshing in the fan when going around corners and stopping.
Drain seems to work fine so not sure what is causing it?

[Dorian]

Colin,
sounds like the evap coil in the cab is freezing up. Once the ice builds up the air doesn't flow thru the coils so the cooling will drop off, also the ice will often block any remaining water in the system, hence the sloshing sound .
If you park it up and there is still water dripping 1/2 hour after you stop then definitely ice-ing up of the evap coils.
The most common common cause of this is there should be a temp switch on the evap coil that stops the compressor is it gets below 2 degrees ( It could be 4 or 6 degrees) . I've had them come off the coil and hanging in the breeze. It could just be it's just soooo humid at the moment.
A short term solution is to stop the aircon for 10 minutes with the fan on high, once the ice melts you'll get another 1/2 hour or so out of the aircon.

Cheers Glen.
