Dorman 973-546 HVAC Blower Motor Resistor Kit

Dorman 973-546 is an HVAC blower motor resistor kit for vehicles with automatic climate control that need replacement of a heat-damaged or corroded resistor circuit. It includes the resistor and a harness pigtail to restore blower speed control on select Chrysler, Dodge, and related applications.

• Includes a blower motor resistor and wire harness pigtail
• 5-wire, 5-terminal design with blade terminals
• Female connector and male terminals for the specified application
• 6-inch wiring harness length
• 2 mounting holes and 2 connector positions
• Direct replacement for overheated or corroded original equipment resistor assemblies

Application Details

This HVAC blower motor resistor kit is built for automatic climate control systems in select Chrysler 300M, Chrysler Concorde, Dodge Intrepid, Chrysler LHS, and Chrysler New Yorker models. It cross-references Monroe Shocks & Struts 172286 and 182286 for the same application. The Dorman 973-546 part number is also commonly searched as a replacement for OE-style HVAC blower resistor repairs.

What It Helps Fix

• Blower motor only working on certain fan speeds
• No cabin air from the HVAC vents at selected settings
• Intermittent blower operation caused by heat damage
• Corroded or damaged resistor connector terminals
• Electrical resistance issues in the blower control circuit

Installation Notes

Verify connector style, terminal count, and harness length before installation. This kit uses a 5-wire harness with blade terminals and a female connector, so matching the original plug and resistor layout is important for proper fitment. Inspect the blower motor connector and surrounding wiring for heat damage before installing the new resistor assembly. Dorman 973-546 is intended for vehicles equipped with automatic climate control, including Chrysler 300M and Dodge Intrepid applications listed in the fitment data.

Quality Assurance

Dorman supplies replacement electrical and HVAC components engineered to match the original service configuration for the listed vehicles. This kit is built as a direct-fit repair solution for the specified Chrysler, Dodge, and Chrysler LHS/New Yorker applications.
