Despite my efforts, neither my Radiator Fan, AC Condensor fan or AC Compressor will turn on. I've let my car idle till the temp gauge is at about 3/4 and the Rad fan won't turn on, and neither the Condensor fan nor the Compressor will respond to the AC button. I've tested the radiator fan with a 12V source and it runs fine.
The AC system has been evacuated, but I can't recharge it without the compressor working. Will the compressor start working once I start charging it? Can a compressor run in a negative system? When I hit the switch, I don't even hear the compressor click or try to start.
All parts should be good, though have never worked before my eyes, so anything is possible. I suspect there's some relay that has gone bad, though near as I can tell all of these systems have their own relays and I refuse to believe that all three have gone bad randomly, unless there is some single cause.
I also should note that I am suspicious of my alternator though I'm not sure how to check it, do I just put a multimeter on the battery (a dry cell moved to the rear btw) when the car is running?
Thanks, if I can resolve this tonight I'll be able to take the car with me back up to UCF tomorrow.
