I may sound silly...so please forgive me in advance!
I noticed that on my 1993 960 wagon, the A/C compressor pulley (wheel where the belt is) is spinning on the outside, but the inner wheel is sticking and not always spinning. Is it absolutely necessary to replace the compressor when this happens, or will a new serpentine belt help, or is there ANYTHING else I could do?

Thanks for your help!!! Amy




I was thinkin about it...and I guess that perhaps I should ask if the inner wheel on the front of the compressor is not supposed to spin all of the time... Is it supposed to spin when the A/C is switched on in the car?? I DO feel silly!!!

 

The center should only spin when the A/C is on.

 

it will only spin when the A/C is on. It will stop occasionally when the A/C is cycling, or if the system is low on refrigerant. If everything is how it should be and it still doesn't work, the A/C clutch is probably slipping and needs to be re-shimmed.
