I've been searching around forums for a few days now and I have been having a really hard time sourcing information for my A/C problems.

My compressor will try to engage when turned on inside the car, but will not spin. I found out when I fried my my A/C idler belt. Is this possibly a fail-safe in the compressor like in the W123's when it runs out of freon? Or is it likely just fired and I need a rebuild or new compressor?

I would like to do the work myself and since I am military so I have A/C equipment to properly work on the system. I am trying to find some A/C info on the W115 but all I have found is the Dieselgiant's DIY for W123.

I also can't find a compressor for sale other than some AC Delco or FOur Seasons. I'd like to stick to the York with the R12.

Any help at all would be great.
