Designed to cut compressor operation when A/C system pressure climbs too high, this Four Seasons switch, part number 36490, is a system-mounted high cut-out pressure switch, also listed as an HVAC cut-off switch. It fits many vehicles, among them the 1993-1995 Dodge Grand Caravan, 1993-1995 Chrysler Town & Country and 1993-1995 Dodge Caravan, as a direct-fit replacement for the listed applications. Engine details are in the Buyer's Guide tab.
As a high cut-out switch, it monitors refrigerant pressure. When pressure exceeds its cut-out point, it is designed to interrupt compressor operation, which helps protect the compressor and other A/C components. Four Seasons engineers and tests its products and draws on more than 50 years of mobile A/C experience.
- Zinc coating: The switch is zinc coated to resist corrosion.
- Vehicle-specific: It is built for specific vehicle applications.
- Sealing parts: It contains gaskets, O-rings or seals as needed to properly replace the product.
- Color coded: Color coding makes it easy to identify.
Signs this switch may need replacing include a compressor that won't engage or that cuts out unexpectedly, or warm air from the vents. These symptoms can have other causes, so diagnose the A/C system first. If a failed high cut-out switch is the cause, this part replaces it.
