any advice on condensation on the inside of my car windows

What part of the A/C function are you talking about, the heating/cooling or the ability to take the moisture out of the air? Mine works just fine on all of these fronts, whatever the temp.

As for the OP, A/C on, full heat, open all the blowers and make sure the recirculate isn't on ( funny circle thing) oh and full fan.

When it is dry, a damn good clean as previously mentioned.

Well the only function of A/C is to provide chilled air, nothing more, anything else is the heating and ventilation system. A side effect of this is to make the air a bit dryer, hence why you get a better demist and also why if you stop using your A/C after using it for a long time the windscreen will mist up due to the moisture that has built up in the ducting.


Also define when your A/C is on, as just because the light is on doesn't mean it is on.

If you don't hear the compressor click then it isn't on.


I will again say that every car I have had since '99 that had A/C hasn't functioned a cold temperatures.

The only reason I know this is that when I first had a car with A/C, i '99, I drove down the road to work and noted that the screen didn't demist, I mentioned this to the dealer at the next service, and he told me that it doesn't function that low to prevent damage to the aircon compressor, I think he said, when I checked the handbook it said it in there.

I admit that different manufacturers might be different, but for the record my wifes Clio does it, my Mondeo does it and my Seat Toledo did it. Don't know about my other cars as I rarely used the A/C in them, as they where petrol and did 8 or 9 mpg less with the A/C on.

Don't leave the damp cloth in the car. The moisture will evaporate from
it and end up on the windscreen again.

I have this problem a lot - a side effect of regularly having 3 of us breathing in a oldish small car (Corsa).

I find the best thing to do when it gets really bad is to wipe down the inside windows then take the cloth in the house to dry/wash to remove any wetness from the car. Same with the foot mats if damp.

Sounds odd but check your air filter for the vents. This was causing problems on my dads old car.

some cars have a little rubber tube in the air intake sections of the ducts in the engine bay these can get leaves in and fill up with water obviously steaming the inside up.

also if you have a sun roof check the drain pipes are exiting via the holes in the floor rather than into the floor

mine sunroof is knackard and leaks into the floor so i just stuck a drill through the carpet and out the floor pan ensuring there were no brake pipes and fuel pipes in the general area

did you try "not breathing...?" seems easier...

Drive with the window slightly open.

What car is it? If it's only a year old I'd take it back to the dealership & ask them to put it right, it sounds like you have water getting into the car somewhere most likely under the front foot-wells where it usually gets in.

Once it starts getting in there the foam layer under the carpet will become more and more saturated and will never dry out.
