Global Parts 1711711 HVAC Blower Motor Resistor

HVAC Blower Motor Resistor for GM Trucks and SUVs

Restore proper blower fan operation with this Global Parts HVAC blower motor resistor, part number 1711711. It is used in GM climate control systems where the resistor helps regulate blower speeds and supports the electrical control strategy used by the vehicle.

This part number 1711711 is a direct-fit style replacement for a wide range of Chevrolet, GMC, and Cadillac applications, including Silverado, Sierra, Tahoe, Yukon, Escalade, and Suburban models.

Key Features

• HVAC blower motor resistor for multi-speed cabin fan control
• Supports engine management feedback in modern vehicle electrical systems
• Used in earlier systems that directly switch compressor operation to help prevent failure
• Fits select Chevrolet Silverado 1500, GMC Sierra 2500 HD, and Cadillac Escalade applications
• Cross-references Standard Ignition RU1064 for the same application

Detailed Description

Global Parts 1711711 is an HVAC blower motor resistor designed for GM vehicles that use resistor-based blower speed control. In the cabin HVAC system, this component helps manage fan speed selection and electrical signaling within the climate control circuit. On newer vehicle systems, the electrical switch provides feedback to the engine management system; on earlier designs, it is used to directly turn the compressor off to help avoid compressor failure. This makes it a practical replacement for diagnosing blower speed loss or inconsistent HVAC operation on supported Chevrolet, GMC, and Cadillac platforms.

Compatible With 2003-2006 Cadillac Escalade, Escalade ESV, and Escalade EXT; 2003-2006 Chevrolet Avalanche 1500, Silverado 1500, Silverado 2500, Silverado 2500 HD, Silverado 3500, Suburban 1500, Suburban 2500, and Tahoe; 2003-2006 GMC Sierra 1500, Sierra 1500 HD, Sierra 2500 HD, Sierra 3500, Yukon, Yukon XL 1500, and Yukon XL 2500; plus select 2000-2002 and 2001-2007 Silverado, Suburban, Yukon, and Yukon XL applications with the listed rear vent or console configurations.

This part cross-references Standard Ignition RU1064 for the same application.

What It Is Used For

• No blower fan speeds or only one fan speed working
• Intermittent cabin airflow from the HVAC system
• Loss of rear vent blower control on supported trucks and SUVs
• Climate control electrical faults tied to the blower resistor circuit
• Compressor control issues on earlier vehicle HVAC systems

Installation Notes and Tips

Verify the vehicle year, make, model, and HVAC configuration before ordering, especially on applications with rear vents or center console notes. Confirm the connector style and mounting location against the original part number 1711711 or the OE reference listed for your vehicle. Inspect the blower motor and related wiring during replacement, since a failing motor or damaged connector can shorten resistor life.
