Sensor, Pressure, Sending Unit, Air Conditioner: 499000-7602 - 3 Year Warranty

Air conditioning pressure sensors, also known as AC switches, turn off a car's air conditioning system whenever the refrigerant pressure reaches a lower extreme. This not only signals the need for a recharge of refrigerant, but also saves the compressor from running without the proper lubrication. If the AC pressure switch is bypassed, then the compressor can potentially freeze up from a lack of fluid and lubrication, requiring expensive work to be done by a professional mechanic.
