There should also be an AC relay, it could be shot.


Here is where things change. I don't have the wiring diagram
for your year but there should only be one line feeding the
compressor clutch. Two wires, but one goes directly to ground.

Check to see which one is which, but you should be able to trip it
with 12 v in either direction. My book shows a Darkblue/yellow stripe
wire being the feed, but that's for a 93 ZJ. YMMV.

Thanks for your help, Doug. I switched the relays with another
identical one with no change. I did note that the relay was warm to
the touch. Is that significant? Next step will be to try to trip it
with 12 volts.

Relays will get a bit warm but shouldn't get too hot. Have you
tracked back all AC fuses? In the ZJ there are two, one in the
primary relay center by the relay and another in the secondary
center inside. Either one will keep the AC from running.
