What Problems Can a Faulty Car Air Conditioning Pressure Switch Cause?

[VonRobert]

When a car's air conditioning pressure switch is damaged, the symptoms include poor contact of the contacts or abnormal operation of the pressure switch, leading to the compressor not working or failing to provide normal pressure protection. Below are specific details about the car air conditioning pressure: 1. Influencing Factors: The pressure value of a car's air conditioning system is generally affected by the surrounding environment, engine speed, condenser cooling conditions, and other factors. 2. Reading Units: Car air conditioning pressure gauges are typically divided into high-pressure and low-pressure gauges, with the red one being the high-pressure gauge and the blue one being the low-pressure gauge. Common reading units on the gauge include megapascals (MPa), bars (bar), kilopascals (kPa), and pounds per square inch (psi). The conversion between these units is 1 MPa = 10 bar = 1000 kPa = 145 psi.
