A-Premium Rear HVAC Blower Motor Resistor 7-Pin Connector for GM SUVs — OE Fit, 1-Year Warranty

If the rear fan in your SUV no longer changes speeds or only runs on high, a failed blower motor resistor is a frequent cause. This A-Premium unit is built to match OE form and fit, uses a 7-pin electrical connector, and is intended to restore multi-speed operation for the rear HVAC blower on supported GM models.

Which vehicles will this rear blower resistor work with?

This resistor fits specific Cadillac, Chevrolet and GMC SUVs and trucks equipped with manual temperature control in the rear HVAC system. Confirm fitment by checking your vehicle year and model or by matching the listed reference numbers to your original part.

• Cadillac Escalade ESV: 2003–2006
• Chevrolet Avalanche 2500: 2002–2006; Suburban 1500/2500: 2000–2006; Tahoe: 2003–2006
• GMC Yukon: 2003–2006; Yukon XL 1500/2500: 2000–2006
• Designed for systems with manual temperature control only

How does the 7-pin connector and installation work?

The unit uses a 7-pin pin-style connector and mounts on the rear side of the HVAC housing with two bolts. It's engineered to OE dimensions so you can swap it in without cutting or splicing wires; simply unplug the old resistor, remove fasteners, and install the replacement in the same orientation.

• Connector type: 7-pin, pin terminal
• Bolt holes: 2 mounting points for secure fit
• Includes wiring harness for easier hookup
• Direct-fit construction reduces installation time and errors
