If your heater and A/C fan has stopped changing speeds, this Dorman blower motor resistor, part number 973-009, is a direct replacement for the front HVAC blower resistor, designed to match the operation and performance of the original equipment. It fits many vehicles, among them the 2003-2006 Chevrolet Silverado 1500, 2003-2006 Chevrolet Silverado 2500 and 2003-2006 GMC Sierra 1500. See the Buyer's Guide tab for the full list.
The resistor controls the current sent to the blower motor, which gives the cabin fan its different speed settings. If a burnt-out resistor is why your fan runs on only one speed or not at all, this unit replaces it.
- Direct replacement: Built to replace the original resistor on the listed applications, with the same fit, function and performance.
- Addresses fan speed problems: Intended for a fan stuck on a single speed or not running at all when the resistor has failed.
- Thoroughly tested: Examined and validated to perform safely and effectively.
- Trustworthy quality: Backed by a team of engineers and inspectors in the United States.
Signs this part may need replacing include a blower that works on only one setting, skips speeds, or will not run at all. A failed blower motor or a wiring fault can cause similar symptoms, so diagnose the cause before you replace this Dorman hvac blower motor resistor.
