An automotive air conditioning system is powered by a compressor. This compressor will turn off and on as needed to operate the system, but problems may occur that cause the compressor to turn off too often, causing the air conditioning system to not work properly.
Low Refrigerant Pressure
Many automotive air conditioning compressors have a low pressure switch that prevents the compressor from running if the pressure level of refrigerant in the system is low. Leaks in air conditioning systems are common, which result in the loss of pressure. If the pressure level is low, the system should be inspected for leaks before being recharged.
The electrical wiring that runs the air conditioning system may become damaged or the contacts corroded, which may cause the compressor to not work properly. The wiring and contacts attached to the compressor should be inspected for problems and repaired as needed.
If the refrigerant levels and electrical wiring all check out, a diagnostic scan should be conducted to determine the source of the problem. Diagnostic scanners can be purchased from an auto part store, but car dealerships and repair shops can often run a more detailed scan.
