How do you jump a 3 pin AC pressure switch?
How To Jump 3 Wire Ac Pressure Switch In Simple Steps
- Reset PCM Fuse. You have to get rid of the PCM fuse to start the repairing procedure.
- Jump AC Relay. Connect the wires according to the numbers printed on it.
- Connect The Charging Connectors. It is essential to remove power before starting the process.
- Open Gas Valves.
Where is the pressure switch on an A / C?
Filter your results by entering your Year, Make, Model to ensure you find the parts that fit your vehicle. The A/C pressure switch is mounted on both the high and low sides of your A/C. When the pressure in your A/C rises or lowers too much, this switch turns off the compressor to protect it and the rest of the system from damage.
Where are the low and high pressure switches on a car?
The low-pressure side switch is found before the AC compressor, while the high-pressure switch comes after the compressor. Most AC pressure switches are found within the engine compartment, but some manufacturers put them elsewhere.
Why is my a / C pressure switch not working?
Compressor clutch won’t engage because the switch inactivates the clutch circuit. Will be charging on the low pressure side of the system, but nothing will happen until I cant get the compressor running. You can still add refrigerant into the low side and it will bring system pressures up so the clutch will engage.
Do you need to unscrew a pressure switch?
Loose the switch with a socket or wrench, then unscrew it. Note: Typically, the A/C system does not need to be evacuated prior to removing the A/C pressure switch. This is because there is a schrader valve built into the switch mount.

Why is there a high and low pressure switch on an AC unit?
Air conditioning pressure switches are designed to protect the A/C system against pressure that is too high or too low. There are both high pressure and low pressure switches; some vehicles are equipped with just a high pressure switch while others have both. Incorrect pressure can damage the compressor, hoses, and other A/C system components.
