Precautions to Take When Replacing
a Blower Motor
The blower motor is typically located behind the glove box on the passenger side and is responsible for blowing hot or cold air into the vehicle cabin or to defrost the front windshield. There are some precautions to take when replacing the blower motor. It’s common to find debris from the environment, such as twigs and leaves, around the blower motor housing. When replacing the blower motor, some of this debris may fall into the new blower motor housing causing irregular noises. This is most common in early model vehicles because there are less barriers for environmental debris. As debris collects, a foul odor may be noticed in addition to irregular noises. This can be easily prevented by cleaning the area surrounding the blower motor housing.
Most late model vehicles use a cabin air filter, typically located above the blower motor housing. Refer to gpd Tech Tip #153, “Precautions to Take When Replacing a Cabin Air Filter”.
