A/C Compressor Cut-Off Switch for 1999-2006 Chevrolet Silverado 1500 & More - Four Seasons 35974

Help protect your A/C system from excessive pressure with the Four Seasons switch 35974, a compressor-mounted high cut-out pressure switch, also listed as an A/C compressor cut-off switch. It is designed to interrupt compressor operation when refrigerant pressure climbs too high. It is a direct-fit replacement for many vehicles, among them the 1999-2006 Chevrolet Silverado 1500, 1988-1999 Chevrolet C1500 and 1988-1999 Chevrolet K1500. See the "Vehicles it fits" section for the full list and engine details.

• Corrosion resistance: Zinc coated to resist corrosion.
• Updated terminal design: An improved 2-terminal design replaces the older 1-terminal switch.
• Sealing components included: Comes with the gaskets, O-rings or seals needed to replace the switch properly.
• Easy identification: Color coded so the switch is easy to identify.

Four Seasons engineers and tests its products and brings more than 50 years of mobile A/C experience to this switch. When a high cut-out switch fails, the compressor may not engage or may cycle off when it shouldn't. A leak may also appear at the switch. These symptoms can have other causes, so diagnose the A/C system before replacing parts. If a faulty cut-out switch is the cause, the 35974 replaces it. A/C work may require the refrigerant to be recovered, so follow the vehicle service information during installation.
