My 2007 Nitro the AC has quit working most of the time. The compressor clutch will engage for a couple seconds then disengage. I hooked gauges to the system, jumped clutch directly to battery and it engages and the pressures are normal for the outside temp. It will cool while doing this. Also I checked the voltage coming to the compressor with the connector disconnected and it is about .8V below battery voltage. The wiring diagram shows it is controlled thru the TIPM. Also when I go to high blower the blower stops. Anyone have a clue?
