Solution

1. Preparation

Gather tools including a socket set, flathead screwdriver, and multimeter.
Disconnect the vehicle battery to prevent any electrical shorts during the repair.

2. Check and Replace Fuse

Locate the fuse box and identify the power window fuse according to the owner's manual.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse for continuity; replace it if it's blown with a new fuse of the same amperage.

3. Repair or Replace Window Switch

Remove the door panel using a flathead screwdriver to pry off clips gently.
Disconnect the window switch connector and inspect for damage.
If necessary, replace the window switch with a new one. Reverse the removal steps to reinstall.

4. Test Power Window Motor

Access the window motor by removing the door panel as described above.
Disconnect the motor connector and use a multimeter to check for voltage when the switch is activated.
If there’s no voltage, the issue may lie with the wiring or switch. If there is voltage, replace the window motor.

5. Inspect and Repair Window Regulator

If the motor is operational, examine the window regulator for any obstructions or damage.
Remove the regulator if necessary, lubricate moving parts, and replace any broken components.
Reinstall the regulator and secure it properly.
