Detailed Description

This Dorman blower motor resistor kit, part number 973-409, is made for front HVAC applications on 1999-2007 Chevrolet Silverado, Tahoe, Suburban, Avalanche, Cadillac Escalade, and GMC Sierra, Yukon, and Yukon XL models listed below. It replaces an overheated or corroded original resistor and restores proper blower motor speed control in vehicles with manual air conditioning controls or no air conditioning, depending on the exact application. The included harness pigtail helps address heat-damaged connector terminals at the same time as the resistor repair.

Common Problems This Repair Can Address

  • Blower motor works on only one or a few fan speeds
  • No cabin airflow from the HVAC blower on manual control systems
  • Heat-damaged or corroded resistor connector terminals
  • Intermittent blower operation caused by a failing resistor circuit
  • Connector melting or poor electrical contact at the resistor plug

Installation Notes and Tips

  • Verify the vehicle uses manual air conditioning controls or the no-A/C configuration shown in the fitment data before ordering.
  • Inspect the blower resistor connector for heat damage before installation; replace the harness pigtail when terminals are discolored, loose, or corroded.
  • Use the included instructions and butt connectors to complete the wiring repair.
  • Confirm the resistor mounting location and connector style match the original part before installation.

Quality Assurance

Dorman designs this HVAC blower motor resistor kit as a replacement for the original equipment part on the listed Chevrolet, GMC, and Cadillac applications. Part number 973-409 is built to restore blower speed control after resistor or connector failure in the specified front HVAC systems.
