Detailed Product Information

This Global Parts relay, part number 1711966, is built for vehicles that use an electronically controlled A/C compressor circuit. In modern systems, the ECM manages compressor engagement through the relay; in earlier designs, the relay can interrupt compressor operation to help prevent failure. It is a practical replacement for Ford F-150, Ford Fusion, Ford Focus, Lincoln MKZ, and other listed applications that require a 4-pin A/C compressor control relay.

Compatible With 2006-2012 Ford Fusion, 2007-2012 Ford Focus, 2006-2008 Ford F-150, and other listed Ford, Lincoln, Mercury, and Econoline applications. Part number 1711966 also interchanges with 5L3T-AA and 5L3TAA.

Common Issues This Relay May Address

• A/C compressor not engaging
• Intermittent compressor cycling
• Loss of cooling due to relay failure
• ECM command not reaching the compressor circuit
• Faulty HVAC relay operation in the A/C control system

Installation Notes and Tips

Verify the relay cavity, pin count, and connector style before installation. Confirm the vehicle uses a 4-pin A/C compressor control relay and match the part number to the original relay or service information. After installation, test A/C operation, compressor engagement, and system cycling to confirm proper function.
