Key Features

• HVAC blower motor resistor harness for select factory applications
• Supports electrical switching used in modern and earlier A/C control systems
• Direct-fit replacement for listed vehicle applications
• Cross-references S1619 and SW-822 for the same application
• Part number: 1712774

Detailed Description

This Global Parts HVAC blower motor resistor harness is designed for vehicles where the A/C system relies on an electrical switch signal for control feedback. In modern systems, the ECM manages A/C operation; in earlier systems, the switch can directly shut off the compressor to help prevent compressor failure. Use this harness when servicing the blower motor resistor circuit on compatible Chevrolet Impala, Ford Fusion, Lincoln MKZ, Mercury Milan, Buick LaCrosse, Pontiac Grand Prix, and other listed models. Part number 1712774 is also referenced by S1619 and SW-822.
