Global Parts 1711522 HVAC Pressure Switch

HVAC Pressure Switch for Ford and Lincoln

Global Parts 1711522 is an HVAC pressure switch used in A/C control systems to send pressure feedback to the engine management system. On modern vehicles, that signal helps the ECM manage compressor operation; on earlier systems, it can directly shut the compressor off to reduce the risk of failure.

• HVAC pressure switch for A/C system pressure monitoring
• Supports ECM-controlled compressor operation on later vehicles
• Used to trigger compressor cut-out on earlier applications
• Direct replacement for select Ford and Lincoln HVAC systems
• Part number: 1711522

Detailed Application Information

Compatible With 2003-2006 Ford Expedition, HVAC Pressure Switch - High Pressure Cutout; 2003-2006 Lincoln Navigator, HVAC Pressure Switch - High Pressure Cutout; 2003-2005 Lincoln Aviator, HVAC Pressure Switch - High Pressure Cutout; and 2000-2002 Lincoln Navigator, A/C Compressor Cut-Out Switch. This Global Parts 1711522 pressure switch is built for vehicles that rely on accurate refrigerant pressure feedback to protect the compressor and maintain proper A/C system control. This part number 1711522 is also cross-referenced to Dorman - OE Solutions 904-626 for the same application.

What It Helps Address

• A/C compressor cycling that is tied to pressure switch input
• Compressor shutoff caused by incorrect high-pressure readings
• Loss of ECM feedback for HVAC pressure monitoring
• High-pressure cutout faults in Ford Expedition and Lincoln Navigator systems
• Intermittent A/C operation on Lincoln Aviator and Navigator models

Installation Notes and Tips

Verify the original switch style and connector match before installation. Confirm the vehicle year, make, and model against the listed applications for Ford Expedition, Lincoln Navigator, and Lincoln Aviator. After replacement, check A/C system operation and scan for HVAC or ECM-related fault codes if the vehicle is equipped with diagnostic monitoring.
