Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle's battery to ensure safety while working on electrical components.

2. Inspect and Replace Fuse

Locate the fuse box under the dashboard or in the engine compartment.
Identify the power window fuse using the diagram on the fuse box cover.
Remove the fuse and inspect it for continuity.
- If blown, replace it with a fuse of the same amperage.
- Reconnect the battery and test the windows.

3. Test and Replace Window Switch

Remove the window switch panel using a trim removal tool.
Disconnect the electrical connector for the switch.
Use a multimeter to check for continuity when pressing the switch.
- If there is no continuity, replace the switch.
Reinstall the new switch and reconnect the battery.

4. Check and Replace Window Motor

Remove the door panel to access the window motor.
Disconnect the motor connector.
Use the multimeter to verify power at the connector when the switch is activated.
- If no power is present, check wiring.
- If power is present, the motor may need replacement.
Remove the old motor and install the new one, ensuring it is secured properly.
Reconnect the window assembly and door panel.

5. Reassemble and Test

Reinstall the door panel and any trim pieces removed during the process.
Reconnect the vehicle's battery.
Test all windows to ensure proper operation.
