What should I do if my GMC AC clutch does not engage?
Disconnect the clear connector from the Vehicle Control Module (VCM). Connect a fused jumper wire between cavity 1(dark green wire with a white stripe) of VCM clear connector and ground. Turn the Ignition Switch to the Run position. Listen for an audible click from the A/C Compressor Clutch. Does the clutch click? If so:
What to do if an A / C compressor clutch does not disengage?
A/C compressors are difficult to work with because of the refrigerant stored inside. When a compressor clutch does not disengage, it will cause the refrigerant to build up and freeze the line. To disengage the clutch, a switch must be replaced.
Why is there no activation of a / C CLUTCH?
There was no activation of a/c clutch. Chevy Mechanic: Dan, ASE Certified Technician replied 10 years ago Remove the relay for the AC. There should be two power terminals, and one terminal going to the compressor and the other one going to pin 1 of that clear connector on that circuit.
What kind of clutch does a 1999 GMC Suburban have?
My 1999 GMC Suburban’s AC clutch is not engaging. I bypassed all pressure switches. The relay will not engage. The jump relay and AC works. Submitted:10 years ago. Category: Chevy Show More Show Less Ask Your Own Chevy Question Share this conversation Answered in 18 minutes by: .
Why is the a / C CLUTCH not engaging in my Ford Ranger?
The A/C requires a enough pressure on the low side to engage the clutch. It protects itself in the event there isn’t enough R134. Put a gauge on the low side (the side nearest the coolant overflow/washer bottle) and see where it’s at.
A/C compressors are difficult to work with because of the refrigerant stored inside. When a compressor clutch does not disengage, it will cause the refrigerant to build up and freeze the line. To disengage the clutch, a switch must be replaced.
Why is the AC clutch not engaging when the switch is turned on?
The AC clutch is not engaging when the switch is turned on. I have checked the fuse-Good, I have swapped relays-Good. But there is no power going to the compressor plug. Is there something between the relay and the compressor that would cause a loss of power?
Where is the low side pressure switch on a Ford Ranger?
The low-side pressure switch is only 1 of 3 switches (OK, 1 of those is a relay) that need to work before the compressor clutch gets power. You can bypass a switch with a paperclip CAREFULLY shoved into the rear of the switch connector, or unplug it and shove the paperclip into the front of the connector.
