Help guard your A/C system against excessive high-side pressure with this Four Seasons switch, part number 36493. It is a system-mounted high cut-out pressure switch, designed to shut off compressor operation when refrigerant pressure climbs too high. It fits many vehicles, among them the 1994-1997 Dodge Ram 1500, 1994-1998 Jeep Grand Cherokee and 1994-1997 Dodge Ram 2500, as a direct-fit replacement for the listed applications. See the Buyer's Guide tab for the full list.
The switch monitors pressure on the high side of the air-conditioning system. If pressure rises past its cut-out point, it interrupts compressor operation, which helps protect the rest of the system from over-pressure. It is also listed as an HVAC cut-off switch. The Four Seasons line is backed by more than 50 years of mobile A/C experience.
- Corrosion protection: Zinc coated to resist corrosion.
- Vehicle-specific: Built for specific vehicle applications.
- Sealing included: Contains the gaskets, O-rings, or seals needed to properly replace the switch.
- Easy identification: Color coded so it is easy to identify.
Signs this switch may need replacing include a compressor that won't engage, an A/C system that cuts out unexpectedly, or refrigerant leaking at the switch. Diagnose the system before replacing parts, because these symptoms can have other causes.
