Four Seasons 37817 HVAC Pressure Switch

The Four Seasons Pressure Switch 37817 is a system-mounted HVAC pressure switch built for high cut-out control in automotive air conditioning systems. It uses a yellow, oval female connector with 2 terminals and an M10 fitting thread size for direct service replacement in the HVAC circuit.

Key Features

  • Four Seasons Pressure Switch line for HVAC pressure control

Product Details

Four Seasons 37817 is an HVAC pressure switch used to monitor refrigerant system pressure and trigger the proper control response when pressure reaches the specified cutoff point. This pressure switch is built as a system-mounted unit and is specified with a high cut-out setting, making it a direct-fit service part for vehicles that use this connector and thread configuration. For buyers searching for an HVAC pressure switch for Honda Civic, Toyota Camry, or Ford F-150 service applications, the key match points are the M10 thread, yellow oval female connector, and 2-terminal layout. This part cross-references Gates 1310 for the same application.

Common Issues This Part Addresses

  • Air conditioning compressor cycling at the wrong pressure point
  • HVAC system shutdown caused by a failed pressure switch
  • Refrigerant pressure signal loss to the control circuit
  • Intermittent A/C operation related to switch contact wear
  • Incorrect high-pressure cutoff response in the HVAC system

Installation Notes and Tips

Verify the connector shape, terminal count, and M10 thread size before installation. Confirm the pressure specification matches the vehicle’s original HVAC switch requirements, and inspect the system for refrigerant leaks or wiring damage before replacing the switch. Fits only the applications that use this exact pressure switch configuration; no vehicle fitment data was provided in the catalog record.

Quality Assurance

Four Seasons lists this pressure switch as meeting or exceeding OEM requirements, supporting service replacement use in automotive HVAC systems.
