Help your A/C system keep track of refrigerant pressure with the Four Seasons HVAC Pressure Transducer / Switch, part number 20955. It fits many vehicles, among them the 1990-1994 Chevrolet Cavalier, 1990-1993 Chevrolet Beretta and 1990-1993 Chevrolet Corsica. See the Buyer's Guide tab for the full list. This system-mounted pressure transducer is also cataloged as a switch, so you may find it listed under either name.
Mounted on the A/C system, a pressure transducer senses refrigerant pressure and converts it into a signal the vehicle uses to help manage compressor operation. Four Seasons engineers and tests its products and draws on more than 50 years of mobile A/C experience.
- Corrosion resistance: zinc coated to resist corrosion.
- Vehicle-specific: a direct-fit replacement for the listed applications.
- Seals in the box: contains the gaskets, O-rings or seals needed to properly replace the product.
- Easy identification: color coded so it is simple to pick out.
Signs this part may need replacing include an A/C compressor that won't engage or cycles erratically, or warm air from the vents. Low refrigerant and other components can cause the same symptoms, so diagnose the cause before replacing. If a failed pressure transducer is the cause, this unit replaces it. Consult the vehicle service information for the correct A/C service and installation procedure.
