Is there a fuse or relay for the compressor clutch?
Is there a fuse or relay for the compressor clutch?
There is no fuse or relay for the compressor clutch. Power for the compressor clutch comes from one of the TIPM circuit boards, through connector C1, pin 50. However, the A/C control panel, among other things, gets power from fuse M34. That may be related. Check for power at the connector on the compressor clutch.
What to do if there is no power to an A / C compressor?
Re: No power to a/c compressor, I have checked the fuses,… The trigger from the dash switch activates the relay which in turn switches on the solenoid pulley to engage the compressor to work. If this circuit is traced the fault of a open circuit can be found out. If there is no power in the fuse or relay then the main wiring must be checked.
Where is the fuse on an A / C compressor?
Go to connector 3 of your PCM (third connector in from driver fender). Pull dust cover off and using a wire tap or backprobe (sharpened paper clip) connect to the blu/org wire in cavity 11 and ground it while running. If the compressor turns on the TIPM, fuses, etc are ok.
Is the high pressure sensor on my compressor leaking?
The high pressure sensor or o-rings on the firewall connector are known to leak. If you trust your dealer or there are visual signs of leakage on the compressor replace it. If not you may have the system charged and have dye added. The dye glows green under a florescent light.

Where is the a / C fuse on a Chevy Silverado?
If you test for 12 volts at the A/C relay terminals (engine compartment fuse block, left side fender) you should detect voltage at two of the four terminals which are marked (30) and (86). That’s power from the A/C fuse and Ignition fuse E, respectively.
Why is my air conditioner clutch not getting power?
Air Conditioning Compressor Clutch Not Getting Power (electrical Ok. Here it goes! No power to AC Compressor Clutch. Here are the details: After researching this I’m thinking it could be the relay in the CCRM (constant control module)? Although I can’t find a good enough diagram to find it!
When to turn on the a / C compressor in a truck?
Once the pressure is about 300 psi it will tell the engine to turn the fan on. If the a/c pressure continues to rise over about 350 the body controller will log an a/c high pressure fault which will lock out the a/c operation until the next key cycle. Does your fan come on at all?
Why is my a / C not working in my truck?
High pressure sensor could be a likely culprit. The body controller will monitor the a/c system pressure through the high pressure sensor. Once the pressure is about 300 psi it will tell the engine to turn the fan on.
