did you try unplugging the switch and using a jumper to get the compressor to start? I did that to get the thing to go after it had sat a while.

I guess I should ask if you have gauges and if the system has pressure in it. Does it have a 134a conversion or are you running r12 still?

With car running a.c. control on max Check power to a.c. clutch unplug the pig tail to clutch and measure with vol. If you have 12 v. And sufficient pressure in system the clutch is
ng. If no power relay is usual suspect but check for gnawed wires.
