ACDelco Blower Motor Resistor

The ACDelco Blower Motor Resistor (also called a blower motor speed control resistor or HVAC blower resistor) controls the speed of your vehicle's heating and air conditioning blower fan. It works by regulating the electrical current that reaches the blower motor. This gives you the different fan speeds you select on the climate control panel.

Key Features:

• Regulates blower motor current to deliver multiple fan speed settings
• Designed to restore proper HVAC airflow when the original resistor fails
• Built to meet ACDelco's quality standards for reliable operation and durability
• Backed by ACDelco, General Motors' parts brand, which has a long reputation in replacement automotive components

Common signs of a failing resistor: the blower works only on some speeds (often high only), the fan doesn't run at all, or the fan speed is inconsistent. Replacing the resistor can restore normal climate control operation.
