Air Conditioning Concerns...
 

Hey everyone, I have a question. I have remote start on my xB, so in the summer when I turn my car off, I usually leave the air conditioner on, so that I can start the car and let it get cool before getting in it. I get in my xB this morning and notice a terrible mildewy smell. I then notice that the driver and passenger carpets are wet. It rained the night before, so I thought it was a leak with the windows. I call the service dept. at my Scion dealership, and they tell me that they see this alot with xB's, and that's its not the windows, its the air conditioning?! Has or does anyone have this problem? Is it because I leave the air conditioner on when the car is not running?! I'd appreciate any help or advice you guys have!!
Thanks!

it';s just that the drain moves or leaks before it's regular drip spot under the car. i believe the drain is situated below/next to the passenger side floor.

Never notice any wet spots but when the A/C is on, then I leave the car, come back and I get the smell from the A/C vents. Had tha same problem with my Toyota truck.

It wasn't just a little spot, the carpets were really wet.

yeah it happens. the drain tube needs to be repositioned and the carpets dried out or replaced.

Yes--I read another post where the owner had this problem and the drain was not situated properly. This should be a warranty issue--make sure you have no mildew or rust problem because of this...........

...and for those odd smells from the A/C:

Happened to me years ago on a Rabbit. The warm moist air in the car condenses on the cold evaporator under the dash. The evaporator is in an air box that collects the condensate water. There is a drain tube that goes down below the floor and drips the condensate on the ground.

Either (a) the drain tube has come off the box, or has come out of the hole in the floor, so the condensate is dripping into the car, or (b) the drain tube has becom plugged up with mold or debris and air box has filled up with condensate and leaked or overflowed.

You will have to raise the xB to get under it to see and reach the drain tube. You can very gently run a piece of stiff wire or coat hanger up through it to ream out any crud that may be plugging it. That worked for the Rabbit for awhile. But if the condensate box has debris or mold in it, it will likely plug the drain tube again. And if the drain tube has come off the box, it will need to be reattached.

I don't know how to see the xB evaporator box to see if its drain tube has come off. If you remove the glove box (see thread for changing cabin filter), you can maybe see an air box under the dash. It will have refrigerant lines and air ducts going into and out of it.

My Rabbit's leak kept coming back after reaming the drain. I figured the air box was growing mold, so I drilled a little hole in the upper side of it and sprayed in Simple Green and other cleaners, which stopped the problem. I am not suggesting that can or should be done with our Scions. I would talk to the dealer some more.
