How To Replace Window Motor?

Posted by Mariios on June 14, 2024

Replacing a window motor in your car might seem hard, but you can do it with a few basic tools. Just remove parts in order, take out the faulty motor, and put in a new one.

Electric windows have been in many cars for years and usually work well. However, if you hear grinding noises or the window moves slowly, the motor might have problems. If the window stops moving completely, it’s time to replace the motor from professional auto glass repair technicians. 

To successfully replace the window motor, you will need:

  • A basic socket set
  • A screwdriver
  • Plastic pry tools
  • Tape or a marker
  • A rubber mallet. 

First, you must remove the door panel by carefully taking off the door handle and screws. Next, you have to access the motor by removing any plastic film and the window glass. Now, disconnect and remove the old motor. Install the new motor and reconnect all components. After the replacement, you may test the motor to ensure it works properly. Finally, reassemble the door by putting the plastic film back, reinstalling the glass, and securing the door panel with all screws and trim pieces.

6 Easy Steps To Replace Window Motor

Here are the detailed steps to guide you better. 

1. Take Off The Door Panel

The first step is to access the motor by removing the door panel. 

  • For classic cars, this means removing the door handle using a tool to release the C clip holding the handle. Then, unscrew the screws securing the door panel, which might be hidden behind fabric buttons.
  • For Modern Cars, the process is similar but more complicated. The manufacturer often hides the retaining pieces behind decorative trim which makes this part hard. You can check YouTube or car forums for specific instructions on your car’s door panel. A set of plastic pry tools will help remove the trim without damage.

2. Access The Window Motor

The next step in replacing a window motor is to access the regulator as well as the motor. You must peel off any black plastic film in the way and set it aside. This film is weatherproofing and must be replaced before putting the door panel back on. If needed, you can remove the radio speaker to get better access to the motor. It is also recommended that the window glass be removed. The glass is held by metal pieces and bolts hence, it is advised to mark the glass position with a tape or marker, then loosen the bolts and gently lift out the glass, setting it aside safely.

3. Remove the Window Motor

Now, unplug the motor’s wires. Take out the bolts holding the motor. Carefully wiggle the regulator and motor out of the door.

4. Put In The New Motor

Now is the time to replace the window motor with a new one. Put the new motor and regulator inside the door panel. Attach them to the mounts. Tighten all the connections and pieces. Connect the electrical connectors.

After the motor and cable are bolted in, put the glass window back in place. Use the marks you made earlier to guide you. Tighten the bolts to secure the glass.

5. Check The Motor

Now, test the motor to see if it works. Make sure the window fits in the frame and closes properly on the weather stripping. If there are gaps, loosen the bolts and move the window gently until it seals tightly.

6. Reassemble Everything Back

The final step is to put back the plastic film and speakers, ensuring everything is in its place. Then, reattach the interior door panel by pushing in the retaining pins with a rubber mallet or your hand’s heel. Replace the bolts and all the trim pieces to secure the door panel firmly.


So this is how you can replace the window motor. It might seem tricky, but it’s manageable with basic tools. Electric windows are common and usually work well, but if they make odd noises or move slowly, it is an indication that the motor might be failing.

To replace it, start by removing the door panel carefully, access the motor and regulator, and remove the old motor. Then install the new one, test it, and reassemble the door panel securely with all parts in place.
