What do you need to know about AC low pressure switch?
Before we talk about how to change the AC low-pressure switch, we have to know about the symptoms of a faulty AC pressure switch. The AC pressure switch is a device mounted on the high and low side of the AC. It monitors the pressure of the refrigerant on both sides of the system.
Where is the pressure switch on an AC unit?
Step 1: Locate the A/C pressure switch. The pressure switch can be mounted to A/C pressure line, compressor or accumulator/drier. Step 1: Disconnect the negative battery cable.

Why is there a pressure switch on my AC?
AC splits into two halves, one is low pressure half and the other is high pressure and both sides are equipped with an AC pressure switch. They are very important safety devices that are built into the AC system because if the pressure is too low or too high, it can cause serious damage to the AC system.
Where are the low and high AC pressure switches located?
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. A look in your service manual will show you the appropriate location for your model.
