What are the symptoms of a failed blower motor resistor?

Blower motor resistor problems. Problems with a blower motor resistor are common in many cars. The most common symptom of a failed blower motor resistor is when the heater fan only runs at high speed and doesn’t work at low speeds.

Where is the resistor on a blower housing?

With the glove box removed, you will see it mounted face down on the right side of the blower housing. The electrical connector plugs into the center of the resistor and points straight down. Disconnect the electrical connector. Remove the two Phillips screws that attach the resistor to the blower housing.

How is the speed of the blower motor controlled?

The blower resistor is connected in series to the blower fan motor. This means that the current running through the blower motor, and its’ speed is therefore controlled by the resistor value. The user chooses a fan speed by selecting a speed which then connects one of the resistors in the blower resistor pack.
