Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, flathead screwdriver, and a Phillips screwdriver.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Fuse

Locate the fuse box; refer to the owner’s manual for the specific location of the power window fuse.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse; replace it with a new one of the same amperage if it is blown.

3. Test and Replace Window Switch

Remove the trim panel around the window switch using a flathead screwdriver.
Disconnect the wiring harness from the switch.
Use a multimeter to check for continuity across the switch terminals while pressing the switch.
If faulty, replace with a new window switch by reversing the removal steps.
