C5 air conditioning issue
My AC stopped working. Before it quit, there was an intermittant "metallic sound" coming from engine when started, not like a bad bearing, more like a loose piece of metal "rattling". Which makes me believe it is the air-conditioning clutch. The AC on light only stays on for 2-3 seconds, then goes off. The CURRENT code is : 60 -IPC U1160.
Any suggestions??

Now, the AC compressor will NOT engage, so there is NO noise. I have the AUTO Temp, option, so I do have the 99-HVAC module, yet there are NO codes showing up for any issues with AC??...maybe just low freon, or whatever the gas is called now 134-a ?? And no current codes on any other module...and there is a fault sensor for the clutch...

Without any ac codes, it sounds to me like the compressor clutch went bad. If there was low freon, you would get a code. This is pretty common. Some of them have problems with the clutch engaged, and others have problems while not engaged. Probably time for a new compressor.
