Dorman 973-004 HVAC Blower Motor Resistor

Restore proper cabin airflow and temperature control with this direct replacement HVAC blower motor resistor from Dorman. Built to match original equipment operation on select Chevrolet and GMC trucks and SUVs, it addresses common blower speed failures tied to a burnt-out resistor.

Key Features

  • Direct replacement blower motor resistor for OE-style fit and function
  • Blade terminal type for the specified vehicle applications
  • Designed for front HVAC systems on select Chevrolet Silverado, GMC Sierra, Tahoe, Yukon, and related models
  • Package contents include the blower motor resistor and instructions

Detailed Description

Dorman 973-004 is an HVAC blower motor resistor made for vehicles that use manual blower speed control or specific front HVAC configurations. When the original resistor burns out, blower speeds can stop working correctly or the fan may only operate on certain settings. This replacement is engineered to restore normal heating and cooling performance in applications such as 1999-2007 Chevrolet Silverado, 1999-2007 GMC Sierra, and related Cadillac Escalade, Tahoe, Yukon, and Suburban models.

Fits 1999-2002 Chevrolet Silverado, front, and 2003-2006 Chevrolet Silverado, front, with manual air conditioning controls or RPO Code D07 where listed. Fits 1999-2002 GMC Sierra, front, and 2003-2006 GMC Sierra, front, with manual air conditioning controls or RPO Code D07 where listed. Fits 2000-2002 Chevrolet Tahoe, front, with manual air conditioning controls.

What It Helps Fix

  • Blower motor works only on certain speed settings
  • No cabin airflow from the HVAC system
  • Intermittent fan operation
  • Loss of heating or cooling output through the vents
  • Failed resistor caused by heat damage or burnout

Installation Notes and Tips

Verify the vehicle’s HVAC control type, RPO code, and front application before ordering. This part uses blade terminals and does not include mounting hardware. Follow the included instructions and inspect the blower motor connector and wiring for heat damage before installing the new resistor.

Quality Assurance

Dorman designs this replacement resistor to match the operation and performance of the original equipment on the listed vehicles. It is built as a direct replacement for the specified front HVAC applications and is intended to restore normal blower control after the original unit fails.
