Is there an automotive section in these fourms? I have had to try to repair a few car/truck AC units and I haven't seen info here on how to repair auto systems.

I currently have a 1997 GMC Jimmy that is leaking 134a from the compressor and would like more info on how to repair these systems.

I am bidding on a new compressor on ebay, but I don't have many auto fittings and no vacuum pump.
