How do you jump the low presure switch with the engine running and AC turned on to find out if the compresser is good?
Depending on the vehicle, lets use a Chevrolet for an example, there is a 2 connecter plug going into the drier/accum. Make a jumper with a short piece of 14 gauge wire and 2 8mm end tips. Place a jumper lead into each hole on the harness side of the connecter. Start the car and carefully moniter pressure. It is possible to damage the compresser by running the system empty, wet or without oil, so make sure you have completed a vacuum test and have an empty system that will pull the freon and oil in quickly. Once you reach normal operating pressures disconnect your jumpers and reinstall the plug. The clutch should cycle on its own now.
