Thread: Condensation around Air Con - 2001 Defender.

I notice in high humidity areas my Rangie will do the same thing. Any part of the dash that gets cold has condensation forming. I don't think there is anything that can be done about it.

If air con is functioning properly, I think this will only occur if the air at the vent 0 degrees or less - most unlikely in a L/R system. The little moisture that's there freezes. Hold a thermometer near the vent & see.

Otherwise you've got a problem if its not taking the moisture out - compressor, receiver/drier, something.

I have only ever seen it drip out via the drains one side of my car (passenger) and I believe my second one is blocked so I will fix that today, but does this happen with anyone else.

I am talking about allot of condensation, dripping off around the air outlets...

Any one else affected ? Ideas ?

Thanks, Cameron

This is normally caused by a few things, undercharge of refrigerant, this makes the coil too cold, this is the most common cause, or the coil is dirty/slighly blocked causing restricted airflow and ice will start to form, this will cool the air too much. Or the fan is not pushing enough air, giving the same result as the blocked coil.

Try running the fan on full, and if you have a temp probe check the temp of the air leaving the vent.

oh it blows heaps of air, but the aircon is COOOLD .. I always have it at max temp (ie the coldest the knob goes) ....

Is there any home remedy / check / thing to clean etc ?z

I do not have a temp prob .. I do have one I use to check the temp on my fridge, will that work ? .. what should it be ?

Listen to Ladas - he da man for aircon

First thing would be to turn down the temp controller a bit, but there is another stat under the passenger footwell kickcover, but really you shouldn't need to adjust that.

If you have loads of air, then my suggestion is that the gas charge is too low and unless you have a set of ref gauges it's not something you can check at home.

But I would get it checked, as reduced gas charge can lead to ice forming on the coil, this can actually split the coil.

ok, when I get a chance I will head to my local aircon guy and ask him to check everything over ..

Another thing you may want to check is to see if the compressor cycles off and on when it gets cold in the cab, best time to check this is at night when it's cooler.

If it doesn't then the thermostat could be buggered.

And depending on which vehicle you have the temp controller on the dash is seldom the thermostat, it's either as I said earlier a seperate stat, on the return air flow between the fan and the cooling coil, or it's controlled by the electronics - and that could be a simple thermistor or alot more complicated.
