How do I get power to my ac compressor its HOT!!!

Huh?


Are you trying to power the compressor in your truck with the truck off? Or..... are you talking about the compressor for your house AC? Is this Lupe?

 

the compressor is run by the belt, a clutch engages to work the compressor. The electrical control of the clutch is done by the combination of the AC switches, and sensors in the system. If there is no freon in the system the clutch will not engage.

 

In most trucks I have been in, there are not really fuses or breakers for the AC system itself. The fans/blowers, yes. If the freon has leaked out the compressor will not work.

 

The refrigerant compressor clutch power comes from a relay signaled by a thermostat switch in the cab and power from a 15A circuit breaker.

Anyway that's the wiring diagram for my older Fr8shakr.

Start tracing wires, buddy!

 

The freon can just be low and the pressure switch will not allow power to the compressor. It's a safety backup to keep from burning it up.

You can follow the low pressure line off the compressor towards the evaporator (firewall). Near the dryer you will find where you add freon. Near it is the pressure switch. You can unplug the pressure switch and run a jumper wire across the male plugin. With all the AC controls on, if the compressor kicks in, you know you are low on freon. If you are low on freon means you got a small leak.

What kind of truck do you have?

 

Did you use a voltage tester or light to verify no power at the compressor clutch. If the clutch is bad it could have power but not be running. Then what everyone else is telling you about the low pressure switch.

I'm not a betting man but would bet that it's got nothing to do with a power problem. I'd do this because of all the A/C problems I have had, it has never been a failure of the wires or fuse/breaker to supply voltage.
