OE-Style Replacement Design

Dorman 973-070 is engineered as a direct replacement for a burnt-out blower motor resistor, helping restore normal heating and cooling fan speeds in the HVAC system.

It is a fitment-based replacement for vehicles such as the Buick LeSabre, Pontiac Bonneville, and Cadillac DeVille, where the front HVAC system uses automatic air conditioning controls.

Common Issues This Part Can Help Solve

  • Blower motor works on only one or a few fan speeds
  • HVAC fan speed control is intermittent
  • Cabin air does not respond correctly to the control switch
  • Heating or cooling airflow is reduced due to resistor failure
  • Front HVAC blower operation is inconsistent on affected Buick, Cadillac, Oldsmobile, and Pontiac models
