96 Corolla AC Power button test? How do I know if any of the 3 relays are not working
I can't get my AC to start. The clutch does not turn when interior AC button is pushed.
There re 3 relays in plastic housing under the hood.
When I put multimeter into small connector to AC pump, I only get ohms reading and no voltage.
I need to replace the AC pump, as the clutch is very loose and flops when turned by hand.
If the belt is on, although the compressor does not engage, it still has a grindy sound while shart turns.
I want to make sure I have voltage to the pump before I replace the entire unit.
Any suggestions to help troubleshoot would be appreciated
