Dorman 984-123 HVAC Blower Motor Resistor - Front

HVAC Blower Motor Resistor for OE-Style Climate Control Repair

Dorman 984-123 is a direct replacement HVAC blower motor resistor for vehicles with automatic or dual-zone climate control. When the original resistor burns out, cabin fan speeds can stop working correctly; this replacement restores proper heating and cooling operation on supported Dodge, Jeep, Chrysler, and Ram applications.

• Direct replacement blower motor resistor for OE-style fit and function
• Designed for vehicles with Automatic Temperature Control (ATC), Climate Control, or Dual Zone Climate Control, depending on application
• Rectangular 1-connector design with 4 blade terminals
• 2 bolt-hole mounting layout for secure installation
• Female connector / male terminal configuration
• Includes blower motor resistor and instructions

Detailed Product Overview

This Dorman HVAC blower motor resistor, part number 984-123, is built to match the original equipment operation on specific Chrysler, Dodge, Jeep, and Ram vehicles. It is used in front HVAC systems where blower speed control is managed through the resistor circuit, helping restore consistent fan output for defrost, heat, and air conditioning performance. This part cross-references Four Seasons 20525 for the same application.

Compatible With select 2007-2019 Dodge Journey, 2011-2018 Ram 2500 and Ram 3500 with dual zone climate control, 2014-2018 Ram ProMaster 1500/2500/3500, 2013-2017 Jeep Compass and Patriot, 2014-2017 Jeep Wrangler RHD, and additional Chrysler, Dodge, Jeep, and Ram models listed below. Part number 984-123 is also referenced in OE-style replacement catalogs for related HVAC repair applications.

Common Problems This Part Can Address

• Blower motor works on only one speed or loses multiple fan speeds
• Cabin heat or A/C airflow is weak, intermittent, or unavailable at certain settings
• HVAC fan control stops responding after the original resistor overheats or burns out
• Defrost performance is reduced because blower output is inconsistent
• Climate control operation is disrupted in vehicles with ATC or dual-zone systems

Installation Notes

Verify connector style, terminal count, and vehicle HVAC configuration before installation. This resistor uses a rectangular female connector with four male blade terminals and mounts with two bolt holes. No wiring harness or mounting hardware is included. Confirm the vehicle is equipped with the listed climate control system, especially on Ram 2500, Ram 3500, Chrysler 200, Dodge Avenger, and Jeep Wrangler applications.
