Re: Jeep Liberty AC Compressor question

This is a real common scenario- seen it numerous times. Clutch air gap has worn too wide such that the magnetic pull of the coil cannot pull in clutch driver after the coil warms- and electrical resistance increases. To prove this, next time it "should be running" tap on front of clutch with a ...
