I was out the other evening and tho it was warm, it was quite humid and I had to turn on the front and rear defrost for a few minutes to clear the windshields.



I was quite pleased to find out the rear defrost works, but the front defrost only works in heat mode. I turned the temp. select dial to full cool, but the temp never went down. After a few minutes I had to shut it off, then turn it back on again as the windshield fogged up. During the off interval, I turned on the AC to see if it worked, and it was fine, so I'm thinking maybe the AC compressor doesn't kick on like it does in newer cars or should I add that to the list of things to see if I can fix?
