This topic wasn't addressed in other fog-related discussions, so here goes.
My windshield and my back window have lately been fogging up excessively, meaning more than other car's windows in my parking lot. Were talking in the morning or evening here, not while I am driving, but after it sits. The back window also frequently fogs up while sitting in the lot at work, for about 5 hours. Again, no other cars around mine have fogged windows.
I have switched between the fresh and re-circulating air switches as mentioned elsewhere on this board, but that doesn't seem to do any good. I know that my AC compressor is on the fritz. Could that be the problem?
