1. Preparation

Gather tools and materials:

Ensure the vehicle is parked on a level surface and is turned off.

2. Remove the Door Panel

Carefully use a trim removal tool to pry off the door panel clips.
Unscrew any visible screws holding the door panel in place (usually located near the handle and the bottom of the panel).
Disconnect any wiring harnesses from the door panel (door lock, window switches).
Gently lift the door panel away from the door frame and set it aside.

3. Inspect and Replace Components

Window Motor:
- Locate the window motor attached to the window regulator.
- Disconnect the motor’s wiring harness.
- Remove the mounting bolts and take out the motor.
- Install the new motor by reversing the removal steps and reconnecting the wiring.
Window Switch:
- Remove the switch from the door panel.
- Disconnect the wiring harness.
- Install the new switch by connecting the wiring and securing it back into place.

4. Reassemble the Door Panel

Reattach the door panel by aligning it with the door frame and pressing it back into place.
Reinstall any screws and reconnect wiring harnesses for the switches and locks.
Ensure all clips are securely fastened.

5. Test the Windows

With the door panel reassembled, test each window switch to ensure proper operation.
Verify that the windows go up and down smoothly without any obstruction.
