I have a 1996 Intrepid (3.5L) and the 10amp A/C Fuse keeps blowing after about 20 minutes. This happens with either the fan and A/C are on or off. Blower fan runs at all speed. I changed the Manual Temperature Control and the results are the same. When the fuse blows, I can't control the temperature or turn on the rear window defroster. Where ever the Air Conditioner/Heater settings is at when the fuse blows is where it is going to be. Right now I've got it in the defrost. I took it to a shop and they can't figure out why it is doing this. Any knows what is going on?
