I've noticed that when its cold outside and i turn the heat on, no matter what setting its on, defrost, floor, panell, etc, the windows fog up almost instantly. This is really dangerous when im driving because as soon as I touch the heat control, I can't see outside anymore. I've noticed that if i turn the AC on to full right away, the clear up in a few seconds, but this is still dangerous, especially since I do a lot of highway driving.

Anybody else have this problem?
any advice ?

Please Help Me !!!!

well my thought is it could be a bad heatercore, but i could be wrong, but that usaly cause's this problem. it is a pain to replace cuz it is like under the dash in most car's not to sure about the contour. but that is all i can think of. hope this helps.

If the heater core were leaking, the film would be very difficult to remove and the defroster would not clear it.

The problem is moisture in the ductwork, most likely caused by a clogged or restricted evaporator drain.

Does the carpet on the passenger side get wet after extend operation of the A/C system? Another common symptom of a clogged drain.

The drain is accessed from below the car. A bent coat hanger will usually clear it. The drain is a hole in the firewall (may have a tube or hose on it) below the lower A/C evaporator line.

please be careful with the coat hanger thou only gently put in in the hole and not to deep(it's a virgin) lol j/k. But you want to make sure you don't go commando and force it in there cuz you could cause quite the mess seeing as the heater core and evaperator core are right there.

I was driving home one night from my gf's house and i put on the heat to defog, and the whole windshield fogged up and my bumper and wheel hit a telephone pole, snapped the wheel sideways , bent the frame , and totaled my old 98 se ... Then i got my SVT and i put the ac on cold then on hot, it makes a difference and the windshield doesnt fog up as bad
