Having problems with your 1993 Cadillac DeVille ?
93 cadillac deville. ac blowing hot. only one pound of freon but compressor wont kick on to allow for charging. where is the relay for the compressor, or what am i missing here? thanks
There is a sensor inline on one of the hoses or on the ac evaporator that should have 2 wires. Unplug the sensor and take a short piece of wire and make a U shape with it and plug it into both ends to complete the circuit on the wired side not the sensor. This will trick the AC pump to turn on. You will also be adding the can or two of freon. If the pump does not turn on after tricking it there may be a problem with the pump or a problem with wiring or the temp control.
