AC no working 700 1991

If your system is low on freon then the compressor or radiator fan won't run. If your a/c system has the pressure switch mounted on the receiver/drier(silver can mounted on the passenger side fire wall) then remove the connector from the switch and momentarily jump the 2 terminals in the connector with a piece of heavy wire. If the compressor and fan runs then your a/c system is low on freon, the pressure switch is bad, or you have an electrical problem with the wiring up to the switch(check for 12 volts at either of the wires in the connector you unplugged, you should have power at one of the wires). Let us know what you find. John
