Detailed Product Overview

The Autotecnica GM0616713 HVAC blower motor resistor is a replacement part for GM heating and air conditioning systems that have lost one or more fan speeds. It is commonly used on Chevrolet Impala and Trailblazer, GMC Sierra and Yukon, and Buick LaCrosse and Rainier applications, along with several Cadillac, Pontiac, Saab, and Oldsmobile models listed in the fitment data. The direct-fit design supports straightforward replacement of the original resistor module without modification.

This part cross-references Dorman OE Solutions 973-508 and Standard Ignition RU-631 for the same application. Autotecnica GM0616713 is also listed under multiple OE and aftermarket interchange numbers for GM HVAC repair work.

What It Helps Fix

• Blower motor stuck on one speed
• Loss of low, medium, or high fan settings
• Intermittent cabin airflow from the vents
• HVAC fan operation affected by heat-related resistor failure
• Climate control performance issues tied to a failed resistor module

Installation Notes

Verify connector style, terminal count, and vehicle HVAC configuration before installation. This resistor uses blade pins, a female connector, and male/female terminal gender layout, so matching the original part is important for proper fit. Confirm front HVAC placement and any climate-control notes shown in the fitment data, especially on Trailblazer, Envoy, Sierra, and Yukon applications.
