I have a 1994 integra. I'm having trouble trying to find what is costing the problem with my ac system. My compressor clutch won't engage and my ac fan won't work. The first thing I did was check the fuse insde the car and it was blown. I ran the car to see if my radiator fan would work and both fan worked. Then I tryed the a/c and notice my a/c fan wouldn't come on along with the compressor clucth. I can't figure it out. I check the compressor realy and the a/c fan relay and both relay are working. I check for voltages at the both a/c fan, compressor relay connectors and the power circuit has voltages. I checked for voltages on the the control ciruit of the a/c fan, compressor relay connectors and I don't have votages with the ignition key on. Does any one have any advice that can help? How do i find the problem?
