How does a resistor pack work on an interior fan motor?
This means that the current running through the blower motor, and thus is speed is controlled by the resistor value. The lower the resistance of the selected resistor in a pack, the higher the current that flows through the blower fan, and the faster the fan will turn.
Why is my heater blower motor resistor not working?
This occurs due to the failed blower motor resistor not being able to control the flow of electric current, it could be that the resistor is somehow bypassed and the power is directly being fed from the switch. Excessive current can overheat and permanently damage the blower motor resistor
What’s the name of the motor that turns the heater?
When the heating or air conditioning in your car is turned on, the fan turns on and forces air out of the car’s vents. The motor that turns the blower is called the blower motor.
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. In the 2008-2011 Ford F150 the blower motor resistor is also located behind the glove box, but is installed in the right side of the plastic air duct.
What does the blower motor resistor do in a car?
The blower motor resistor is an electrical component that is a part of the vehicle’s heating and air conditioning system. It is responsible for controlling the blower motor’s fan speed. When fan speed is changed via the knob on the instrument cluster, the blower motor resistor changes setting, which changes the speed of the blower motor.
When to replace AC fan speed resistor 98-04?
Buy Now! When your blower motor for the AC and heat isnt working on all settings then chances are your blower motor resistor has failed. This is usually do to moisture from the cabin air box corroding the electrical component. Here we’ll show you how to repair it and if you’re in need of a new one, check out 1AAuto.com.
What happens when a heater motor resistor fails?
If the resistor shorts or fails, it may cause the blower motor to remain stuck on one fan speed. The heating and air conditioning systems may still function at one speed, however the resistor will have to be replaced in order for full functionality to be restored. 2. Blower motor does not work on certain settings
