Keep your air conditioning compressor clutch cycling on and off as it should with this Four Seasons switch, part number 20922, a system-mounted cycling pressure switch that monitors A/C system pressure. It fits many vehicles, among them the 1998-2002 Dodge Ram 1500, the 1998-2006 Jeep Wrangler and the 1998-2002 Dodge Ram 2500, and it is a direct-fit replacement for the listed applications. See the "Vehicles it fits" section for the full list and engine details.
The switch senses refrigerant pressure and signals the compressor clutch to engage or disengage. This helps the A/C system cycle as designed and helps keep the evaporator from icing up.
- Corrosion resistance: A zinc coating helps the switch resist corrosion.
- Vehicle-specific: Built for specific vehicle applications rather than as a universal part.
- Seals supplied: Comes with the gaskets, O-rings or seals needed to properly replace the product.
- Color coded: Color coding makes the switch easy to identify.
Four Seasons engineers and tests its products and has more than 50 years of experience in mobile A/C.
Signs this switch may need replacing include a compressor clutch that cycles on and off rapidly, a clutch that will not engage, or warm air from the vents. Low refrigerant or a clutch fault can cause the same symptoms, so diagnose the system first. If the cycling switch is the cause, this part replaces it.
