Function of an AC Pressure Switch
The purpose of the AC pressure switch is to give the system a safety monitor. It is in charge of keeping track of the refrigerant levels on the AC unit's high- and low-pressure sides.
You have two different AC pressure switches on your car for this reason. While the other is assessing the low-pressure elements, one is keeping an eye on the high-pressure side.
The pressure will never fall too low thanks to the low-pressure switch. When there is a leak, this issue arises. Without the proper pressure, the AC compressor can sustain serious damage from pumping out refrigerant, which will increase the expense of repairs.
The high-pressure AC switch keeps track of any systemic obstructions that could increase pressure. There may be an eruption in the system if the pressure rises too much. In order to prevent further pressure build-up, the switch instructs the system to turn off electricity to the air conditioning.
Where is the AC Pressure Switch?
On either side of the air conditioner are the pressure switches for the AC. One switch is located on the high side, and the other is located on the low side.
The high-pressure side switch is located after the AC compressor, whereas the low-pressure side switch is located before it.
While some manufacturers place their AC pressure switches somewhere else, the majority are located in the engine compartment. You may find the right spot for your model by consulting the service handbook for your vehicle.
