How It Works

The blower motor resistor regulates voltage to the HVAC blower motor so the fan can operate at multiple speeds. On modern vehicles, the ECM may manage A/C system operation; on earlier vehicles, related electrical switching functions were used to help protect the compressor from failure. Global Parts 1711709 is built for vehicles that need this type of blower motor resistor service, including Chevrolet Blazer and GMC Sonoma applications.

This part cross-references Dorman OE Solutions 973-005 and Standard Ignition RU1027 for the same application.

Common Problems It Can Help Solve

• Blower fan works on only one speed
• Intermittent cabin airflow from the HVAC vents
• No response from lower fan speed settings
• Weak or inconsistent heater and A/C blower operation
• Loss of proper HVAC fan control in GM truck and SUV systems

Installation Notes

Verify the connector style and vehicle application before installation. Inspect the blower motor, wiring connector, and related HVAC components for heat damage or corrosion, since a failed resistor can be caused by excess current draw or connector wear. Confirm fitment for your specific Chevrolet S10, GMC Jimmy, or Oldsmobile Bravada before replacing the part.
