Help protect your air conditioning compressor with the Four Seasons switch 35970, a compressor-mounted low cut-out pressure switch, also listed as an A/C compressor cut-off switch, designed to interrupt compressor operation when refrigerant pressure in the system falls too low. It fits many vehicles, among them the 1999-2011 Chevrolet Silverado 1500, 1988-2001 Chevrolet C1500 and 1988-1999 Chevrolet K1500, as a direct-fit replacement for the listed applications. See the "Vehicles it fits" section for the full list.
Four Seasons engineers and tests its products and backs them with over 50 years of mobile A/C experience. This switch brings these features:
- Zinc coating: The switch is zinc coated to resist corrosion.
- Two-terminal design: An improved two-terminal design replaces the older one-terminal switch.
- Seals in the box: It comes with the gaskets, O-rings or seals needed to properly replace the switch.
- Color coded: Color coding makes the switch easy to identify.
Signs this switch may need replacing include a compressor that will not engage or that cycles on and off erratically. Low refrigerant charge and wiring faults can cause the same symptoms, so diagnose the A/C system before replacing parts. If a failed low cut-out switch is the cause, this part replaces it. Follow the vehicle service information for removal, installation and refrigerant handling.
