I have a 86 berlinetta camaro recently everytime i would put a fuse in the fan fuse slot when I turn the key it would blow the fuse, I swapped out a relay under the hood and the fuse didnt pop, now my Ac will not engage the compressor! I have just recently fixed the Ac and recharged it. THe low pressure switch has no power. I swapped in a 383 vortec stroker and had the Ac working, any ideas? Fuses under dash are fine. Coolant fan turns on with key without ac
