Re: Air Conditioner Help Needed
 

Thanks for the wiring diagram, Bill!

I believe I connected (jumped) the low pressure and the high pressure
switches with the same result - clutch did not engage. Would I need
to jump them both at the same time? I did not do that.

Thanks again.

The possibility of both switches being bad at the same time would
be like winning the lottery.

Yes, you'll need to check to see which one is connected to the body of the
compressor and which one goes to the clutch coil. When you're sure you've
got the one to the clutch, connect it to 12V while the engine is running,
and the compressor should start. If it doesn't, you've either got a bad
ground (not too likely) or bad compressor clutch. If it doesn't start,
connect a jumper from the frame to the body of the compressor and try it
again. No start = no clutch. If it started with just the 12V, you can
backtrack through the system via the compressor relay, etc. (Jeep's
wiring seems a bit convoluted, but Bill's wiring diagram should
make it fairly easy if you are good at schematics.)

Make sure your low pressure cutoff switch is not open This switch protects
the compressor should there be a loss of refridgerant. You can by pass this
switch for testing but only for a few seconds to see it the compressor
starts.
