Question: AC compressor does not work
Question
Airconditioning does not work, heating works fine. Compressor was not working, so replaced it with new unit. No power at compressor. Also noticed I do not have out side temp. and engine temp indication. For engine temp. replaced coolant temp sensor/sender unit, but no help.
Fuel tank indicator is also at E, regardless fuel tank is full or half.

MasterFor the A/C issue, we at RepairPal put together an inspection sheet to help folks with these types of problems.

The gauge issues are a separate inspection, best to have the Instrument Panel scanned.
