Dorman 904-612 A/C Pressure Switch

Restore A/C system control with this Dorman HVAC pressure switch for Ford and Lincoln applications. The Dorman 904-612 is a specific-fit replacement A/C transducer switch for vehicles using R134A refrigerant, built to address failed terminals or a damaged connector on the original sensor.

Key Features

  • Specific-fit HVAC pressure switch for select Ford and Lincoln vehicles
  • Designed for R134A air conditioning systems
  • 5-volt sensor with 3-pin male terminals and female rectangular connector
  • Metal housing with bolt-on mounting and 10 mm thread diameter
  • Pressure limits: closed at 260 PSI and open at 475 PSI
  • Maximum pressure reading of 500 PSI
  • Black connector and black housing for OE-style replacement

Product Details

This HVAC pressure switch monitors A/C pressure and sends the signal needed for proper system operation. When the original sensor has corroded terminals, a broken connector, or inaccurate pressure readings, the Dorman 904-612 provides a direct replacement path for restoring air conditioning function. It cross-references Four Seasons 37340 for the same application. Common fitment includes Ford F-150, Ford Explorer, Ford Edge, Ford Mustang, Ford Transit, and Lincoln Navigator applications.

Common Problems It Can Solve

  • Air conditioning compressor not engaging
  • Intermittent A/C operation caused by poor electrical connection
  • Corroded or damaged pressure switch terminals
  • Broken original connector at the transducer switch
  • Incorrect pressure signal affecting HVAC system control

Installation Notes

Verify the connector style, thread diameter, and refrigerant system before installation. This part uses a bolt mount and a 10 mm thread diameter, with no mounting bracket included. Confirm vehicle-specific HVAC configuration and match the original sensor connector before replacement.
