Safety Warnings: Disconnect the negative terminal of the battery to prevent electrical shorts.

2. Inspect and Replace the Fuse

Locate the fuse box under the dashboard or in the engine compartment.
Remove the power window fuse using a fuse puller or pliers.
Check the fuse for continuity using a multimeter.
Replace with a new fuse of the same amperage if blown.

3. Remove the Door Panel

Use a screwdriver to remove screws securing the door panel.
Carefully pry off the door panel using a trim removal tool to avoid damaging clips.
Disconnect the electrical connectors from the window switch and any other components attached to the panel.

4. Test the Power Window Switch

Using a multimeter, check for continuity at the window switch terminals when pressed.
If no continuity is detected, replace the power window switch.

5. Test and Replace the Window Motor (if necessary)

Disconnect the window motor wiring harness.
