Solution

1. Preparation

Tools Required:
- Screwdrivers (flathead and Phillips)
- Multimeter
- Socket set
- Trim removal tool
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check and Replace the Fuse

Locate the fuse box (refer to the owner's manual for location).
Remove the power window fuse using a fuse puller.
Inspect the fuse for continuity. If blown, replace it with a new fuse of the same amperage (usually 30A).

3. Replace the Window Switch (if defective)

Remove the trim panel around the window switch using a trim removal tool.
Disconnect the window switch connector.
Install the new switch by connecting the harness and reinstalling the trim panel.

4. Replace the Window Motor (if defective)

Remove the door panel by unscrewing bolts and using a trim removal tool to detach clips.
Disconnect all wiring from the door panel and remove it completely.
Locate the window motor and disconnect its wiring harness.
Remove the motor mounting screws using a socket set.
Install the new motor by reversing the removal steps, ensuring it is securely mounted.

5. Reassemble Door Components

Reattach the door panel by aligning it correctly and securing it with screws and clips.
Reconnect the negative battery terminal.
