Install the electrical wire connector. Install the under-dash panel that was removed under the glove compartment and install the 7mm screws.
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.
Where is the blower motor resistor located on a Ford Escape?
In the 2008-2011 Ford Escape, the resistor is located behind the glove box on top of the HVAC unit air duct. It’s held by two screws and is easy to replace. See the photo.

Remove the screws that secure the blower motor resistor to the housing… and put them someplace safe. At this point, you can remove the resistor from the housing. Take your new resistor… put it in position… and install it using the screws that held the old resistor in place.
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.

Why is the blower motor not working on my car?
My car has an automatic transmission. Hi There, The resistor is what controls the speed of the blower motor, not the relay. The blower motor relay supplies power to this motor when you turn the switch to “on” that can sometimes fail. When this happens, you may notice that you will not feel anything blowing out of the vents at all.
