Has your blower motor resistor burnt out? If a failed resistor is why your heating and cooling fan has stopped changing speeds, this direct replacement is designed to match the operation and performance of the original equipment on the listed applications. This Dorman hvac blower motor resistor is listed for both front and rear positions.
- Direct replacement: Built to match the fit, function and performance of the original part on the listed applications.
- Addresses fan-speed faults: If a bad resistor leaves the fan running on only one speed, or not at all, this unit replaces it.
- Thoroughly tested: Examined and validated for safe, effective operation.
- Trustworthy quality: Supported by a team of engineers and inspectors in the United States.
Signs a resistor may need replacing include a fan that works on only one speed or a fan that does not run at all. A faulty switch, motor or wiring can cause the same symptoms, so diagnose the cause before replacing parts.
