Anyone who operates a GMC knows that when it comes to repairing their car, truck, or SUV only the highest quality replacement parts will do. Obviously, you didn't buy your Sierra 3500 HD unless you understood you would be getting horsepower and rugged design both impeccably combined into one vehicle. When your GMC Sierra 3500 HD left the factory, it was destined for a person with discerning taste who values trusted quality in their automobile. The vehicle in your driveway is head and shoulders above the rest compared to all the other cars, trucks, and SUVs these days.
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 HD blower motor resistor modulates the resistance applied to the circuit that handles the load of the blower motor. When you command your GMC Sierra 3500 HD heater to blow on "High", it lowers the resistance so that all the amperage reaches the blower. And when you switch to low, the heater blower motor resistor raises resistance so that less amperage reaches the blower motor.
