ACDelco GM Original Equipment HVAC Blower Motor Resistor

The ACDelco GM Original Equipment HVAC Blower Motor Resistor (also called a blower motor speed control resistor or blower resistor) controls the fan speed of your heating and air conditioning system. It regulates the electrical current sent to the blower motor, so you can select the airflow setting you want for heating, cooling and defrosting.

Key Features:

• GM Original Equipment part, engineered to meet GM specifications for fit, form and function
• Restores the full range of blower speed settings when the original resistor has failed
• Built for dependable electrical performance in the heat and vibration of the HVAC system
• Backed by ACDelco, GM's trusted parts brand
• Direct replacement design that installs without modification

Common signs of a failing blower motor resistor include a blower that works only on the highest speed, a fan that works on some speeds but not others, or no airflow at all. Replacing the resistor can restore normal climate control operation and comfort. Choose the specific part number in this product line that matches your application.
