Global Parts 1712664 HVAC Heater Core Temperature Sensor

HVAC Heater Core Temperature Sensor for Ford

Global Parts 1712664 is an HVAC heater core temperature sensor used in the climate control system to send temperature feedback to the engine management system. On modern vehicles, that feedback helps the ECM manage A/C operation; on earlier systems, it can directly shut the compressor off to help prevent compressor damage.

Compatible With 2005-2007 Ford Five Hundred and 2005 Ford Freestyle applications, this sensor is a direct-fit service part for vehicles that need accurate HVAC temperature input. Part number 1712664 is also a useful reference when matching the correct replacement.

Key Features

• HVAC heater core temperature sensor for climate control feedback
• Supports ECM-controlled A/C system operation
• Used in systems that monitor temperature to protect the compressor
• Fits 2005-2007 Ford Five Hundred, N/A
• Fits 2005 Ford Freestyle, N/A
• Part number 1712664 for easy identification

Detailed Description

This Global Parts sensor is built for Ford HVAC systems that rely on temperature feedback from the heater core circuit. It helps the control system read temperature conditions and respond appropriately, whether that means managing compressor operation through the ECM or triggering compressor shutdown in older designs. This part cross-references Standard Ignition AX211 for the same application.

Use 1712664 when servicing Ford Five Hundred and Ford Freestyle climate control systems that require a heater core temperature sensor. The part number 1712664 can also help confirm the correct replacement during diagnosis or parts lookup.

What It Helps Solve

• Incorrect HVAC temperature feedback to the control system
• A/C compressor shutdown caused by sensor-related faults
• Climate control behavior tied to heater core temperature readings
• Diagnostic trouble conditions related to HVAC sensor input
• Replacement needs for Ford Five Hundred and Ford Freestyle HVAC service

Installation Notes and Tips
