Solution

1. Preparation

Gather tools: socket set, multimeter, flat-head screwdriver, Torx screwdriver, and replacement fuses (if needed).
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Check and Replace Fuse

Locate the fuse box (typically found under the dashboard or in the engine compartment).
Refer to the fuse box diagram to find the power window fuse.
Remove the fuse using a fuse puller or pliers, and inspect it for continuity. Replace if blown.

3. Inspect and Replace Power Window Switch

Remove the door panel using a flat-head screwdriver and Torx screwdriver.
Disconnect the wiring harness from the power window switch.
Use a multimeter to check for continuity across the switch terminals.
If faulty, replace the power window switch with a new unit.

4. Test and Replace Window Motor

Access the window motor by removing the door panel.
Disconnect the wiring harness from the window motor.
Using a multimeter, check for voltage at the motor connector when the window switch is activated.
If there is voltage and the motor does not operate, replace the window motor.

5. Reassemble and Test

Reattach the door panel and ensure all clips and screws are secure.
Reconnect the vehicle battery.
Test the power windows to confirm functionality.
