Product Details

Four Seasons Pressure Switch 37814 is part of the brand’s Pressure switch line for HVAC service and replacement work. This HVAC cut-off switch monitors low-side pressure and opens or closes the circuit at the specified thresholds to help regulate compressor operation. It is a direct-fit style component for pressure-switch service on vehicles such as Honda Civic and similar applications that use an M12, female, system-mounted low cut-out switch. This part cross-references UAC SW11416C for the same application.

What It Helps Solve

  • Compressor cycling caused by incorrect low-side pressure readings
  • A/C shutdown from a failed pressure cut-off switch
  • Intermittent HVAC operation related to switch contact wear
  • Electrical connection issues at the pressure switch connector
  • Replacement needs for a damaged system-mounted HVAC switch

Installation Notes

Verify the connector shape, terminal count, thread size, and pressure thresholds before installation. Confirm the vehicle uses a female M12, 2-terminal, oval connector and a low cut-out pressure switch location. For fitment-based searches, this part is commonly referenced for Honda Civic HVAC pressure switch replacement and similar make/model applications that match the listed specifications.

Quality Assurance

Four Seasons 37814 is manufactured to meet or exceed OEM specifications for pressure-switch service. Confirm all electrical and refrigerant-system details against the original component before installation.
