Four Seasons A/C Compressor Cut-Off Switch P/N:20055
Help protect your A/C compressor against excessive system pressure with this Four Seasons switch, part number 35961, a compressor-mounted high cut-out pressure switch also listed as an A/C compressor cut-off switch. It fits many vehicles, among them the 1988-1995 Chevrolet C1500, 1988-1995 Chevrolet K1500 and 1981-1985 Chevrolet Impala, 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 senses A/C system pressure. It is designed to interrupt compressor operation when pressure climbs past its cut-out point, which helps guard the system against over-pressure conditions.
Four Seasons engineers and tests its products and backs them with more than 50 years of mobile A/C experience. If a failed cut-out switch is why your compressor won't engage or shuts off unexpectedly, this part replaces it. Diagnose the A/C system before replacing parts, and follow the vehicle service information. Replacing a compressor-mounted switch may require recovering the refrigerant with the proper equipment.
