Solution

1. Preparation

Gather necessary tools: OBD-II scanner, multimeter, socket set, and a flathead screwdriver.
Disconnect the vehicle battery to ensure safety during the repair.

2. Inspect and Replace Fuse

Locate the fuse box under the dashboard or in the front trunk.
Identify the specific fuse for the power windows using the fuse box diagram.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse visually; if it appears blown (the metal strip inside is broken), replace it with a new fuse of the same amperage.

3. Test and Replace Window Switch

Remove the window switch panel using a flathead screwdriver to gently pry it up.
Disconnect the wiring harness from the switch panel.
Use a multimeter to check for continuity across the switch terminals.
If the switch is faulty, install a new window switch by reversing the disconnection steps.

4. Inspect Wiring and Window Motor

Trace the wiring harness from the window switch to the window motor for any signs of damage or disconnection.
If the wiring is intact but the window still doesn’t work, access the window motor by removing the door panel.
Test the window motor with a multimeter to check for power supply when the switch is activated.
Replace the window motor if it fails the test.

5. Reassemble and Test

Reattach the door panel securely.
Reconnect the battery.
Test the power windows to confirm they operate correctly after repairs.
