Help protect your A/C compressor from harmful pressure conditions with the Four Seasons System Mounted Binary Pressure Switch, part number 35829, which monitors refrigerant pressure and is designed to interrupt compressor operation when system pressure falls too low or climbs too high. It fits many vehicles, among them the 1988-1990 Toyota Corolla, 1985-1987 Honda Civic and 1985 Honda Accord. See the Buyer's Guide tab for the full list.

  • Corrosion resistance: Zinc coated to resist corrosion.
  • Vehicle-specific design: Built for specific vehicle applications as a direct-fit replacement for the listed applications.
  • Sealing parts included: Contains the gaskets, O-rings or seals needed to properly replace the switch.
  • Easy identification: Color coded so it is simple to pick out.

Four Seasons brings more than 50 years of mobile A/C experience to this switch. A binary switch may need replacing if the A/C compressor won't engage or cycles erratically, or if refrigerant is seeping at the switch. If a failed switch is the cause, this part replaces it. Check the refrigerant charge and wiring first, because they can cause the same symptoms.
