I seem to have a real problem with this in the summer. The inside will start to fog up, I'll put the defroster on to take care of it. If I leave it on too long, the outside starts to get foggy and wet. I'll shut the defrost off and a few minutes later the inside starts foggin again. I'm not talking a long time either. I'm 15 minutes from home to work and I'll have this cycle 4 or 5 times. It doesn't matter if the a/c is on or the windows are open. Same crap. I had the same problem with my 97 SE Sport. Any way to solve this??
