Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, screwdriver set, and wiring repair kit.
Disconnect the negative battery terminal to prevent any electrical shorts while working on the vehicle.

2. Check and Replace Fuses

Locate the fuse box; refer to the owner's manual for the exact location.
Remove the power window fuse (usually labeled) using a fuse puller or pliers.
Inspect the fuse; if it is blown, replace it with a fuse of the same amperage (check the manual for the correct rating).
Reconnect the battery and test the window operation.

3. Inspect and Replace Window Switch

If the fuse is intact, remove the door panel using a screwdriver to access the window switch.
Disconnect the window switch wiring harness and test for continuity using a multimeter.
If faulty, replace the window switch with a new one.
Reassemble the door panel and reconnect the battery.

4. Test Window Motor

If the switch is functioning, access the window motor by removing the door panel.
Disconnect the motor's electrical connector and test for voltage at the connector while pressing the window switch.
If no voltage is detected, check the wiring between the switch and motor.
If voltage is present but the motor does not operate, replace the window motor.

5. Reassemble and Test

After repairs, reattach the door panel securely.
Reconnect the battery and test all windows to ensure proper operation.
