Dorman 973-020 HVAC Blower Motor Resistor

Restore blower speed control in select Dodge Ram and Jeep applications with this direct replacement HVAC blower motor resistor. Dorman 973-020 is built to match the original equipment operating pattern on vehicles that use a blade-terminal resistor design, helping bring back proper heating and cooling fan function.

Key Features

• Direct replacement HVAC blower motor resistor for select Chrysler, Dodge, and Jeep vehicles
• Blade terminal type for the specified factory-style connection
• Package contents include the blower motor resistor and instructions
• Designed to match original equipment operation and performance on covered applications
• Part number 973-020 for easy identification and ordering

Detailed Description

This Dorman blower motor resistor is used in HVAC systems where the blower fan only works on certain speeds or stops responding as expected. It is a practical replacement for Dodge Ram 1500, Ram 2500, and Ram 3500 models from the covered years, as well as Jeep Grand Cherokee and Jeep Grand Wagoneer applications listed in the fitment data. If you are searching for a blower motor resistor for a 1994-2002 Dodge Ram 2500, 1994-2001 Dodge Ram 1500, or 1994-1999 Jeep Grand Cherokee, Dorman 973-020 is the correct OE-style service part for those vehicles.

This part cross-references Monroe Shocks & Struts (e.g., RU109, RU876) for the same application.

What It Helps Fix

• Blower motor works on only one or a few fan speeds
• HVAC fan speed control is intermittent
• No cabin airflow from the heater or A/C blower on selected settings
• Burned or failed blower resistor causing loss of normal climate control operation
• Reduced heating and cooling performance from a malfunctioning blower circuit

Installation Notes and Tips

Verify the terminal style and vehicle fitment before installation. This resistor uses blade terminals and does not include mounting hardware. Follow the included instructions and inspect the blower motor connector and surrounding wiring for heat damage before installing the replacement part. For best results, confirm the application against the vehicle year, make, and model listed in the fitment data for Dodge Ram and Jeep Grand Cherokee service.

Quality Assurance

Dorman supplies direct replacement parts engineered to follow the original equipment design and function for the listed applications. Part number 973-020 is intended for service on the covered Dodge Ram and Jeep vehicles shown in the fitment data.
