Detailed Description
Four Seasons 37314 is a pressure-operated HVAC cut-off switch used to monitor refrigerant system pressure and trigger high-pressure cutoff behavior when needed. The switch is designed for system-mounted installation and features a closed operating state with a high cut-out threshold, helping the A/C system respond to elevated pressure conditions in Volvo 240, Volvo 940, and Volvo 960 applications. If you are searching for a Volvo 940 pressure switch, Volvo 960 HVAC cut-off switch, or Volvo 240 A/C pressure switch, this part number 37314 matches the listed fitment and connection style.
This part cross-references AMS Automotive 4904 for the same application.
What It Helps Address
- A/C compressor shutdown caused by high refrigerant pressure
- Intermittent HVAC operation tied to pressure switch failure
- Incorrect pressure signal to the A/C control circuit
- Loss of system protection during high-pressure conditions
- Fitment issues when replacing a worn Volvo HVAC cut-off switch
Installation Notes and Tips
Verify the 12mm x 1.50 female thread connection, 2-terminal male plug, and system-mounted location before installation. Confirm the vehicle application against the listed fitment for 1992-1995 Volvo 940, 1992-1995 Volvo 960, and 1992-1993 Volvo 240.
