Take it to the shop and let them fix it for you. The part will cost about $300 and so will the labor.
The ac compressor clutch is mounted on the front of the compressor and is a replaceable part. However depending on the complexity of the clutch change out it may be overall better to change the compressor and clutch together.
thats the relay to engage the a/c compressor clutch
How do you change out a air ride compressor on a 2002 Cadillac Escalade?
It is inside the under hood fuse box.
The ac clutch is held on with a single nut, and can be removed with a remover tool. It the tool will not fit in the space available, then the entire compressor will have to be removed to replace the clutch.
you probly need to change your belt. Addition: I have the same problem in my 2002 Xterra. It is the compressor clutch engaging/disengaging during normal opperation of the A/C system. Tightening belts will do nothing for the intermittent squealing belts on a 2002. On most vehicles, you could just change the clutch assembly .... However, not on the 2002 Xterrra. I will need to replace my whole compressor, which sucks b/c my A/C blows perfect cold air. My 2 cents.
This requires special tools to remove and install the ac clutch and bearing. The air gap on the ac clutch must be done during install.
Try jumping the two terminals of the wires which go to the low pressure switch. That's a possibility, as is low refrigerant, a bad compressor clutch, or a faulty fuse or relay to the compressor clutch.
The systems holds 266 ml (9 oz).......
I'm pretty sure the 2002 Silverado has a cycling clutch compressor, which should release the clutch to cycle off when the specified system high pressure has been reached, and cycle back on when it drops to the specified system low pressure. It should not be running at all times.
Locked up compressor, or defective compressor clutch.
It just cost me 760 to replace the whole compressor 300 for a rebuilt part and 300 for labour + I had to get a new belt I'm pretty sure u cAn just get the a/c clutch for half the price
