Solution

1. Preparation

Tools Required:
- Socket set
- Screwdriver set
- Multimeter
- OBD-II scanner
Disconnect the negative battery terminal to prevent electrical shorts while working on the system.

2. Inspect and Replace Fuses

Locate the fuse box (typically under the dashboard or in the engine compartment).
Identify the power window fuse using the fuse diagram found on the cover of the fuse box.
Remove the fuse and inspect it for continuity; replace it if blown (use the same amperage).
Reconnect the battery and test the window operation.

3. Test and Replace the Power Window Switch

Remove the door panel using a screwdriver to access the power window switch.
Disconnect the switch connector and use a multimeter to check for continuity when switches are activated.
If there’s no continuity, replace the switch with a new one.
Reassemble the door panel and reconnect the battery.

4. Inspect and Replace the Window Motor (if needed)

If the switch is functional, access the window motor by removing the door panel.
Disconnect the motor connector and use a multimeter to check for power at the connector when the switch is activated.
If there is power but the motor does not operate, replace the window motor.
Install the new motor, reconnect everything, and reassemble the door panel.
