Yesterday my wife calls to say that AC on the burb is not working. When I got home, I found that the compressor was not spinning. I checked the relay by swapping it with the Starter relay, the relay was okay so I swapped them back to their original spots. I then checked all of the electrical connections, all seemed okay, but the compressor still didn't engage. I then tapped on the center of the compressor (the part that wasn't spinning) while the enging was running and it spun. Everything now works fine.
So I suspect the A/C clutch is going out. Where can I get one at a reasonable cost? Are there any special tools needed to change it? Its a 97 suburban with the ac at the top of the engine.
thanks.
