Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to avoid electrical shorts.
Ensure the workspace is clean and organized.

2. Replace the Fuse

Locate the fuse box and identify the power window fuse using the diagram on the cover.
Remove the fuse using a fuse puller or pliers.
Check the fuse for continuity and replace it with a new fuse of the same amperage if blown.

3. Replace the Power Window Switch

Remove the door panel using a trim removal tool to access the switch.
Disconnect the wiring harness from the old switch.
Install the new power window switch by connecting the wiring harness and securing it in place.
Reattach the door panel and ensure all clips are properly seated.

4. Test the Window Motor

If the switch replacement does not resolve the issue, disconnect the power window motor from the wiring harness.
Use jumper wires to connect the motor directly to the battery, ensuring correct polarity.
If the motor operates, the issue is likely with the switch or wiring; if not, the motor may need replacement.

5. Replace the Window Regulator (if necessary)

If the motor is functional but the window still does not operate, remove the door panel again.
Disconnect the window from the regulator and remove any retaining bolts.
Replace the window regulator with a new unit and reattach the window to the regulator.
Reassemble the door panel.
