Select Your VehicleAnyone who operates a GMC knows that when it comes to repairing their vehicle only the most superior replacement parts will do. Your GMC dealership isn't the only place to locate trusted repair parts to fix your Sierra 3500 Classic. Obviously, you didn't buy your Sierra 3500 Classic unless you knew that you wanted horsepower and rugged design both rolled up into one vehicle. It's not every day that you realize that you have to buy a replacement Blower Motor Regulator Resistor to fix your car or truck.

What Blower Motor Regulator Resistor does for your vehicle.

Multi-speed climate control has been around for decades, and is a convenience we all take for granted. A heater blower resistor gives you the ability to control the level, volume, and speed of the heat and A/C that comes from the vents. Because it is connected directly to the heater switch, your GMC Sierra 3500 Classic blower motor resistor modulates the resistance applied to the circuit that handles the load of the blower motor. When the GMC Sierra 3500 Classic heater switch is set to "Max", there is less resistance in the circuit so more amps go to the blower. And when you switch to low, the heater blower motor resistor raises resistance so that less amperage reaches the blower motor.

The things our company has to make it special.
