I am currently having issues with the fan the blows the air conditioning. It is a 85 camaro sport coupe I was driving then parked and it was working fan. Then I cut the car back on it stopped working. When moving the dial back and forth you can hear the air compressor switch on and off but no fan. I have checked the fuses and there are none that are blown. What are the most probable causes?

 

If you have a volt meter, unplug the wiring harness to the fan and see if it is getting voltage to it (if you can get to it) Is there a relay that could have gone bad? I'm not familiar with whats under the hood where on 85 but that is a few things to consider.
