When a burnt-out resistor has left your cabin fan stuck on one speed, this Dorman blower motor resistor, part number 973-020, is a direct replacement designed to work like the original. It fits many vehicles, among them the 1994-2001 Dodge Ram 1500, 1993-1999 Jeep Grand Cherokee and 1994-2002 Dodge Ram 2500. See the Buyer's Guide tab for the full list and engine details.
This HVAC blower motor resistor controls the voltage sent to the blower motor, which lets the fan run at its different speed settings. If the original resistor has burned out, the fan may run on only one speed or stop working entirely. These are signs this part may need replacing.
- Direct replacement: Built to mirror the original unit's fit, function and performance on the listed applications.
- Heating and cooling support: If a failed resistor is the cause, it addresses a fan that works on only one speed or not at all, so your heating and cooling can work properly again.
- Thoroughly tested: Examined and validated to perform safely and effectively.
- Trustworthy quality: Backed by a team of engineers and inspectors in the United States.
Other faults in the blower circuit can cause the same symptoms, so diagnose the cause before replacing the resistor.
