Ac Low Pressure Switch Location

If you jump the low pressure switch with the engine running do it only for a few seconds.

Ac low pressure switch location.

Identify the faulty ac low pressure switch symptoms ac high pressure switch symptoms. The low pressure switch is designed to shut the compressor. If your ac clutch isn t spin. But usually the sensors are most often located in the engine bay or under the front on the ac condenser on the front of the car.

Jump the low pressure switch only to test the circuit. The location of the refrigerant pressure sensor can differ a lot between car models and depending on whether you are going to replace the high or low pressure sensor. The chevrolet truck uses two air conditioning pressure switches. Low ac pressure will prevent the relay from sending power to the ac compressor clutch.

The ac low pressure sensor is located at the line that runs from the compressor component of the system through the evaporator or the firewall of the system up to the condenser on the low pressure side of the air conditioning system. If the pressure is too low ac low pressure switch the compressor risks damage due to running with low oil. The high pressure switch is designed to shut down the compressor if the line pressure gets dangerously high. Do not jump the low pressure switch to operate the compressor non stop so you can add refrigerant.

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 it is too high ac high pressure switch the compressor is at risk of overheating and becoming damaged. This will usually happen when a condenser fan fails.
