My AC on my black 95 Z28 won't work unless I jump the relay for the compressor to engage. Thinking this might have something to do with my cooling fans being wired directly to my battery. How can I fix this problem without spending a bunch of money?
Have you put an a/c pressure gauge on to see if pressure is high enough to run compressor. Jumping pressure switch to run compressor with low charge can damage it.
www.shbox.com has wiring diagram for fans. Rewire back to stock configuration. If you want to run a fan switch also, shoebox has a wiring diagram for that also.
Not having the fan relays in the system will throw a code and stop compressor from running, but play it safe and check system pressure with compressor running. Only run compressor long enough with pressure switch jumped to confirm system pressure.
