Solution

1. Preparation

Gather tools: fuse puller, multimeter, socket set, and screwdrivers.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Check and Replace Fuse

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Identify the power window fuse by referring to the fuse diagram.
Remove the fuse using a fuse puller and inspect it for continuity.
- If blown, replace it with a new fuse of the same amperage (check owner's manual for specifics).

3. Inspect Window Switch

Remove the window switch panel using a flathead screwdriver to gently pry it up.
Disconnect the switch connector and use a multimeter to check for continuity.
- If faulty, replace the window switch with a new one.

4. Inspect Wiring Harness

Trace the wiring harness from the switch to the window motor.
Look for any frayed wires, corrosion, or loose connections.
- Repair any damaged wiring by splicing and soldering as necessary or replacing the harness.

5. Test and Replace Window Motor

If the switch and wiring are functional, the issue may lie with the window motor.
Remove the door panel (unscrew and unclip) to access the window motor.
Disconnect the motor connector and use a multimeter to check for power when the switch is activated.
- If there is power but no movement, replace the window motor.
