Detailed Description

Dorman 973-189 is an HVAC blower motor resistor engineered for vehicles where the original resistor has failed and fan speeds no longer work correctly. It is a direct replacement for the factory unit and is intended to restore normal heating and cooling blower operation in select Ram 1500, Ram 2500, Ram 3500, Dodge Ram 1500, Dodge Ram 2500, and Dodge Ram 3500 trucks. This part cross-references Mopar 68048900AA for the same application.

Compatible With 2011-2018 Ram 2500, Exc. Climate Control; 2011-2018 Ram 3500, Exc. Climate Control; 2011-2014 Ram 1500, Exc. Climate Control; 2009-2010 Dodge Ram 1500, Exc. Climate Control; 2010 Dodge Ram 2500, Exc. Climate Control; and 2010 Dodge Ram 3500, Exc. Climate Control. The Dorman 973-189 blower motor resistor is a practical OE-style replacement for trucks that need restored blower speed control without changing the HVAC system layout.

Common Issues This Part Can Solve

• Blower motor works only on certain fan speeds
• No cabin airflow from the HVAC vents
• Intermittent heater or A/C blower operation
• Burned or failed blower motor resistor
• Loss of proper defrost and cabin comfort control

Installation Notes and Tips

Verify the connector style, terminal count, and vehicle fitment before installation. This resistor uses a female rectangular connector with blade terminals and does not include a wiring harness or mounting hardware. Confirm the vehicle is not equipped with climate control where excluded by fitment notes. Inspect the blower motor and connector for heat damage before installing the new resistor.

Quality Assurance

Dorman designs replacement parts to match the function of the original component on the listed applications. Part number 973-189 is built for direct-fit service on the specified Ram and Dodge Ram trucks.
