2001 LHS. Windows are fogging up in back. Defrost only on high and still wont clear up. Driver only in car and nothing wet inside. Does this model have an air exchange door that I can get at to check if it is stuck?
Answer:
You have it correct, the recirculation door for outside air is stuck closed and not allowing air to come in causing the fogging condition. The motor for this door is on the passenger side of the heater box. I believe that you can see this if you take the glove box out, but it has been a long time since I've worked on one of these for this issue. It is motor number 2. As I looked at the instructions it says the dash has to come out to get to this motor.
