Solution

1. Preparation

Gather tools: socket set, multimeter, screwdriver set, and OBD-II scanner.
Ensure the vehicle is parked on a stable surface and the ignition is turned off.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Fuses

Locate the fuse box (usually found under the dashboard or in the engine bay).
Remove the cover and inspect the power window fuse (refer to the owner’s manual for exact location).
If the fuse is blown, replace it with a fuse of the same amperage.
Reconnect the battery and test the windows.

3. Test and Replace Window Switches

Remove the armrest cover to access the power window switch assembly.
Disconnect the wiring harness from the switch.
Use a multimeter to test the switch for continuity when pressed.
If the switch is faulty, replace it with a new one.
Reassemble the armrest and test the windows again.

4. Inspect and Replace Window Motor

If the switches are functional, proceed to the window motor.
Remove the door panel by unscrewing any visible screws and gently prying off clips.
Disconnect the window motor wiring harness and test for voltage.
If there is voltage but the motor does not operate, replace the window motor.
Reassemble the door panel and test the window operation.
