HVAC Pressure Switch for Ford and Mercury

Global Parts 1711549 is an HVAC pressure switch that sends pressure feedback to the engine management system. On modern vehicles, the ECM uses this signal to manage A/C operation; on earlier systems, the switch can shut the compressor off to help prevent damage from abnormal pressure conditions.

  • Rectangle connector shape for direct electrical connection
  • HVAC binary operation pressure switch application
  • Supports ECM-controlled A/C system feedback
  • Used in compressor protection strategies on earlier vehicles
  • Global Parts 1711549 replacement for select Ford and Mercury applications

Detailed Product Information

This HVAC pressure switch is built for select Ford Escape, Ford Focus, Mercury Mariner, and Mercury Cougar applications. It monitors refrigerant pressure and communicates that information to the vehicle control system so the A/C system can respond appropriately. Global Parts 1711549 is a practical replacement when the original switch no longer reports pressure correctly or causes inconsistent compressor operation. This part cross-references Four Seasons (e.g., 20891, 20989) for the same application.

Common Problems This Part Can Address

  • A/C compressor cycling on and off at the wrong time
  • No compressor engagement due to pressure signal faults
  • Fault codes related to HVAC pressure input
  • Compressor shutdown caused by a failed pressure switch
  • Intermittent cooling performance in ECM-controlled A/C systems

Installation Notes and Tips

Verify the connector shape is rectangle before installation and compare the original switch to Global Parts 1711549 for connector and application match. Confirm the vehicle uses an HVAC binary operation pressure switch and inspect the electrical connector and surrounding harness for corrosion or damage before replacement. Fits 2008-2012 Ford Escape, N/A. Fits 2002-2007 Ford Focus, N/A. Fits 2008-2009 Mercury Mariner, N/A. Fits 1999 Mercury Cougar, N/A.

Quality Assurance

Global Parts 1711549 is listed with confirmed vehicle fitment for select Ford and Mercury models and is identified as an HVAC pressure switch replacement for those applications.
