I've been having an issue with the windows fogging during the winter. Earlier this year I had the AC system purged and refilled (after adding a can at a time to get the defrost issue to go away, with no success).

I do not smell any coolant, so i do not believe it is a heater core issue. I pulled the display fuse for 5 minutes to reset, so we'll see if that helps at all when the wetter days come.

The AC light turns off when it gets cold out. I hear it should below 34 degF, is that true? During the winter time, the light will be on sometimes, then turn off while I'm driving. From what I can tell, that's when the fogging starts.

Any Ideas?
