My 91 SC A/C stopped working.
I have checked the low pressure switch OK
Hooked up guages have 100psi.
Ran Diags on Climate Control No Errors
Ran jumper to A/C Clutch it Pulls in and I get Cold Air.
I have no Power at the A/C Clutch plug is there a WOT cutoff switch that is open?

Thanks
 
Bypass the low pressure cutout (aka "Cycling Switch") before you hit the WOT relay, but yah, there's a WOT relay (one of the three at the passenger side, against the firewall, to the car's right of the evaporator inlet and accumulator).

You may have three there - one would be a brown one, for the ABS pump, one would be black for the ABS controller, and one is the WOT relay.
