xGM Genuine Parts 15-8788 Blower Motor Resistor for GM Vehicles
When your vehicle’s HVAC blower speed becomes inconsistent or stalls, a failed blower motor resistor is often the culprit. The GM Genuine Parts 15-8788 is designed to restore range and control by modulating voltage to the blower motor, enabling the different fan speeds you rely on daily. This part follows the same engineering intent as the components installed during production, delivering a true OE experience without guessing games about compatibility.
What it does
- Restores blower speed control when the resistor has failed
- Provides multiple fan speeds through stepped voltage delivery to the blower motor
- Designed to work with GM HVAC systems and maintain original performance characteristics
Inside the HVAC system, this resistor works behind the scenes to manage airflow by adjusting the electrical load to the blower. A properly functioning resistor helps maintain steady climate control across various settings, avoiding abrupt changes in airflow that can occur with a degraded component.

Practical considerations and benefits
- Designed for seamless installation in GM vehicles without aftermarket fit issues
- Backed by GM for confidence in long-term reliability and compatibility
As with any maintenance part, results can vary by vehicle condition and usage. This resistor is positioned as a reliable, genuine OE option for GM owners seeking authentic GM components rather than aftermarket substitutes. By restoring proper speed control, it can help maintain comfortable cabin climate without requiring additional diagnostics for the HVAC system.
