A blend door motor is a device that controls the temperature inside your car. Every time you change the heat level on the control panel, the blend door should make the necessary adjustments to let enough warm air in. However, if there you still feel too warm, or too cold, despite all the adjustments you made, chances are the blend door motor has failed you. Replacing it is a simple process that requires minimal tools, and lots of patience.
Difficulty level: Moderate
- Car owner's manual
- Socket set
- Wrench set
- New blend door motor
Step 1: Park your car, and turn off the engine. Disconnect the battery to avoid accidental shocks during the repair.
Step 2: The blend door motor is usually located behind the center console. For most cars, this can be accessed by removing the glove compartment door to expose the insides of the front. Other cars require you to remove interior panels along the center console, or on the sides, to access the electrical wires inside. Refer to your car owner's manual for its exact location.
Step 3: Push aside other devices and wires to make your way to the blend door motor.
Step 4: Once it is in reach, disconnect the electric wires that feed the motor. After getting the wires off, take out the motor itself. There are cars that have blend door motors bolted on the car. Remove these bolts to remove the motor. For some models, the motor is not secured by bolts, and can be easily pulled from its mount.
Step 5: Get your replacement blend door motor, and insert it on its mounting. Guide the motor to properly make contact with the door itself. Screw the bolts remove, if there are any, and reconnect its electrical wires. Return also any other wires and devices removed while making your way to the motor.
Step 6: Before replacing the panels, or glove compartment door, test the new motor first. Reconnect the battery, and start your engine. Move the temperature control and feel if the heat level changes. If you are satisfied with your repair, and the motor appears to be working, finish the repair by reinstalling the panels, or glove door.
The whole process may take about 1 hour.
- Wear safety gloves to protect your hands. You will be working with limited space packed with some sharp edges.
- While doing the blend door motor, it may also be a good idea to check the blend door itself. With some extra steps, and cutting tools, you can see if the blend door also has problems.
