Why is my AC blower not working on my 2006 Silverado?
2006 Silverado 2500HD blower speed control replacement. My brother has a 2006 Silverado 2500HD. The AC blower will not shut off. I know this is probably a bad resistor module under the dash so I ordered a new one. His has 3 wires in and two out to the blower motor.

What happens if the blower motor only works on high speed?
In other designs, the failure of 1 resistor means you lose only one speed. However, most car makers bypass the blower motor resistor completely when you move the fan speed switch to high. If your blower only operates on its highest speed, chances are you have the series type of blower motor resistor. This is the most common failure mode.
How does a blower work on a Chevy Silverado?
I USED A BATTERY CHARGER AND TOUCHED THE PRONGS TO THE E TERMINAL AND ALL OF THE OTHER TERMINALS. E TERMINAL IS THE GROUND AND A,B,C,D,F ARE THE BLOWER SPEEDS. THE FAN SHOULD KICK ON WHEN YOU HIT ANY OF THOSE TERMINALS WITH THE JUMPER CABLE PART OF THE BATTERY CHARGER.
What are the symptoms of a bad blower motor resistor?
Another common symptom of a faulty blower motor resistor is a a blower motor that does not function on certain settings. If the blower motor resistors’ internal components fail it may cause the blower motor to malfunction, or not function at all on one or more of the settings.
What causes a blower motor to stop working?
In a situation where the motor doesn’t work on any speed, the most likely causes are: a blown power supply fuse, a bad motor ground connection, bad motor speed control module or a failed motor. On all systems, a failed blower motor is least likely. Blower motors generally don’t fail out of the clear blue.
How do you fix a blower motor on a car?
Disconnect the electrical connector at the blower motor and jumper power and ground to the motor, bypassing all the speeds controls. Run a fused jumper from the battery to the power side of the motor and connect a temporary grounding jumper to the other motor terminal.
Why did my Chevy Silverado blower plug burn up?
Most aftermarket companies, NAPA CARQUEST ADVANCE will have replacement plugs you can splice in for about half the price of a GM plug kit, and they burn up because GM cheaped out on the size of the terminals and they get hot, when they get hot they loose tension which causes them the get really hot and melt the plastic plug.
How does a half speed blower motor work?
So a half speed driver request will result in the blower motor controller pulsing the ground connection off twice as often as when the fan is running at full speed. Carmakers use these three common wiring methods to supply power and ground to the blower motor in a manual system using a blower motor resistor.
