Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
Hello, since you arent getting power to the compressor, you need to trace the circuit. See if the low pressure switch has battery voltage and jump across the switch if it does. The compressor should come on. If there is no power at the low pressure switch, you may have an issue with the ac clutch relay.
It is a dual pressure switch. Do you have power at two of the ac relay pins when the ac is on? If you jump across the relay will the compressor come on? Do the cooling fans come on when the ac is turned on? The switch is located at the dryer under the hood as shown as number 9 in this attachment
Yes thats fine ill be on for awhile or tomorrow after 2pm PST. CHeck for two power sources at the relay with the ac on
Hello, do you need more help with this concern?
