I have noticed that in addition to the above mentioned problem ,when at idle under load (in drive with brakes applied) or in park the compressor clutch will slip at idle. If I kick up the idle the cltuch will engage. HAs anyone ever changed an A/c compressor clutch with the compressor on the vehicle?
What tools are needed?
BTW, this is the GM R4 compressor and clutch.
