I have a 2004 GT w/ less than 40,000 miles on it. Within the past 4-5 months the fan has been a little temperamental. It just wont turn on, all the controls are set to high and max a/c I'm positive but it just wont turn on unless it wants to sometime later down the road. Quite frankly this sucks if its freezing or hot as ***** and is pretty dangerous if I cant get the defroster going when its raining. If anybody has had this problem or has any ideas what the problem could be and how to fix it, i would really appreciate your input. Thanks a lot, Eric
