• Part number 973-021 for easy identification and ordering

Detailed Description

Dorman 973-021 is an HVAC blower motor resistor designed to restore proper fan-speed control in vehicles with a burnt-out resistor. When the resistor fails, the blower motor may only work on certain speeds or stop responding altogether. This replacement is engineered to match the function of the original part on supported Jeep Wrangler, Jeep Cherokee, and Dodge Ram van applications, including front and rear HVAC positions where listed. This part cross-references Autotecnica DG0613201 for the same application.

Compatible With select 1997-2006 Jeep Wrangler, 1997-2001 Jeep Cherokee, and 1999-2003 Dodge Ram van platforms, this resistor supports OE-style HVAC repair needs without changing the factory control layout. The Dorman 973-021 part number is also useful when searching for a replacement for Jeep Wrangler RHD models and Dodge Ram 1500, 2500, and 3500 van HVAC systems.

What It Helps Fix

• Blower motor works on only one speed
• Loss of low or medium fan settings
• No cabin airflow from the HVAC blower
• Intermittent heating or cooling fan operation
• Failed resistor caused by heat damage or electrical wear

Installation Notes and Tips

Verify the terminal style and vehicle position before installation. This resistor uses blade terminals and does not include mounting hardware. Follow the included instructions and compare the original part number, connector shape, and HVAC location on the vehicle before replacing the unit. Confirm fitment for the exact year, make, model, and front, rear, or RHD application listed for your vehicle.

Quality Assurance

Dorman designs replacement components to match original equipment function on the listed applications. This HVAC blower motor resistor is built as a direct replacement for supported vehicles and is intended to restore factory-style blower speed control.
