Help protect your air conditioning compressor with this Four Seasons switch, the 35757 HVAC cut-off switch / low cut-out pressure switch, a system-mounted unit listed under both names and built as a direct-fit replacement for the listed applications. It fits many vehicles, among them the 1977 Chevrolet Impala, 1976-1979 Chevrolet Nova and 1975-1978 Chevrolet C10. See the Buyer's Guide tab for the full list.

A low cut-out pressure switch monitors pressure in the A/C system. It is designed to interrupt compressor operation when system pressure drops too low, which helps keep the compressor from running without enough refrigerant. If a failed cut-off switch is the cause of a compressor that won't engage or cycles erratically, the 35757 replaces it. Diagnose the system before replacing parts, because low refrigerant and other faults can cause the same symptoms.

  • Corrosion protection: zinc coated to resist corrosion.
  • Vehicle-specific: made for specific vehicle applications, whether you need a switch for the 1975-1978 Chevrolet C10 or for another listed model.
  • Sealing included: comes with the gaskets, O-rings or seals needed to properly replace the switch.
  • Easy to identify: color coded for quick identification.

Four Seasons engineers and tests its products and draws on more than 50 years of mobile A/C experience.
