Ac Low Pressure Switch Location

Do not jump the low pressure switch to operate the compressor non stop so you can add refrigerant.

Ac low pressure switch location.

Check the pressure of the air conditioning system by attaching a low pressure gauge from a refrigerant recharge kit to the low pressure fitting located between the accumulator and the compressor and marked with a capital l according to aa1 car on an 80 degree day the low pressure gauge should measure 56 psi pounds per square inch or higher. If you jump the low pressure switch with the engine running do it only for a few seconds. If it is too high ac high pressure switch the compressor is at risk of overheating and becoming damaged. If you are trying to replace the sensor know that the r 134 a hoses used for recharging will only fit through.

If your ac clutch isn t spin.

The chevrolet truck uses two air conditioning pressure switches.
