Help protect your A/C compressor with this Four Seasons switch, part number 35756, a compressor-mounted low cut-out pressure switch designed to shut off compressor operation when refrigerant pressure drops too low. It fits many vehicles, among them the 1988-2001 Chevrolet C1500, 1999-2001 Chevrolet Silverado 1500 and 1988-1999 Chevrolet K1500, as a direct-fit replacement for the listed applications. See the "Vehicles it fits" section for the full list and engine details.
The switch mounts on the compressor and monitors system pressure. If pressure falls below its cut-out point, it opens the compressor circuit so the compressor does not keep running without adequate refrigerant.
- Corrosion protection: The switch is zinc coated to resist corrosion.
- Improved terminal design: It uses an updated two-terminal layout that replaces the older one-terminal switch.
- Seals included: It comes with the gaskets, O-rings or seals needed to replace the switch properly.
- Easy identification: The switch is color coded so it is easy to identify.
Signs this switch may need replacing include a compressor that will not engage, erratic compressor cycling or an A/C system that blows warm air. Low refrigerant charge and other faults can cause the same symptoms, so diagnose the system before replacing parts. Four Seasons brings more than 50 years of mobile A/C experience to this switch.
