compressor engages on auto.. and econ
92 Deville- When I switch the climate control to off, the compressor disengages. It engages on auto and on econ. I have a 93 deville too, and I swapped the AC relays, but it didn't help. When I disconnect the switch on the accumulator, the clutch stays engaged, and that is supposed to disengage it. The fuse, #7, looks fine. The compressor is brand new, and the old one did the same thing. The previous owner had put a new compressor connector on with two white wires. I tried switching those two wires around and that didn't help either. Having another Caddy almost exactly the same might help, but I think I am going to need to get a voltmeter. Maybe the ground wire has a short to ground, or is it activated by voltage? How do I go about troubleshooting this thing?
