Dorman 973-076 HVAC Blower Motor Resistor Kit

Dorman 973-076 HVAC Blower Motor Resistor Kit

Dorman 973-076 is an HVAC blower motor resistor kit that replaces a failed original resistor and the related harness pigtail on select GM vehicles. It is built for manual HVAC systems where blower speeds stop working, run intermittently, or only operate on certain settings.

Key Features

• Includes a blower motor resistor and wire harness for a complete electrical repair at the connector point
• Uses a 4-terminal, male blade terminal design with a female connector interface
• 6-inch wiring harness length for service replacement at the HVAC connector
• Direct replacement for overheated or corroded original equipment resistor assemblies
• Cross-references Dorman 973-076 for the same application

Detailed Description

This HVAC blower motor resistor kit is made for vehicles that use manual air conditioning controls and need restoration of blower fan speed control. The resistor manages blower motor voltage so the fan can operate at multiple speeds, while the included harness pigtail addresses heat-damaged or corroded connector ends that often fail alongside the resistor. Dorman 973-076 is a practical repair for Buick Skylark, Pontiac Grand Am, Chevrolet Cavalier, Oldsmobile Cutlass Ciera, and other listed applications from 1986-1998.

Compatible With select Buick, Chevrolet, Cadillac, Oldsmobile, and Pontiac models, this part supports common HVAC electrical repairs where the original connector has overheated, loosened, or lost terminal integrity. The package contents include 1 blower motor resistor and 1 wire harness.

Common Problems This Part Can Solve

• Blower motor works on only one speed or loses multiple fan speeds
• Intermittent HVAC fan operation caused by a failing resistor
• Heat damage at the resistor connector or harness pigtail
• Corrosion at the electrical terminals in the blower motor circuit
• Loss of cabin airflow control in manual HVAC systems

Installation Notes and Tips

Verify the vehicle uses manual air conditioning controls before ordering. Inspect the blower motor connector, terminals, and surrounding wiring for heat damage before installation, since a damaged connector can cause repeat failure if not repaired. Confirm the original connector style and terminal count match the replacement part before connecting the harness.
