Is this normal on these cars? In the winter, my windshield gets frost on the inside. When it's humid in the spring, I ALWAYS have to have my defroster on because my windshield fogs up bad. Just wondering if this is a problem, or something these cars normally do.

check the evap drain, maybe its clogged.

That's very possible, and it would make sense because my AC smells musty. I remember reading about a TSB on this issue. Maybe it's clogged and mildewing in there. Never connected the two issues... thanks for the idea!

i don't know where on this car it is, i never looked, but its the drain for all the water that collects from the evaporator for the ac. you know when you have the ac on for like an hour then when you park there is a puddle of water under the car,? that drain.

Mine was doing the same thing, and one day I thought I heard air coming in from the bottom of the windshield?

when was the last time you cleaned the inside of the windshield as that can cause this as well. but what everyone else says probably the evap draining system filling up.

now we gotta find the damn thing!

mine does it too, except in the winter, it freezes on the inside and forms frost, and is a real bitch to defrost
maybe my windshield isnt sealed...

^I hear wind coming from the passenger window, I added double sided tape to make sure the weatherstripping was holding alright so maybe the window isn't adjusted properly..

If you track in snow on your shoes, the water melts which gives water vapor on the inside of your car, which will gather on the windshield. That happens a lot on my car...

I had this problem and it was because my sunroof track was broken letting moisture in and fogging up my front and back windows most of the time.

so where is this evap drain?
