Solution

1. Preparation

Gather tools and parts required.
Disconnect the vehicle's 12V battery to ensure safety while working on electrical components.

2. Inspect and Replace Fuse

Locate the fuse box; it is usually found under the dashboard.
Remove the cover and identify the power window fuse (refer to the owner's manual for specific location).
Use a multimeter to check for continuity. If blown, replace it with a new fuse of the same amperage.

3. Test and Replace Window Switch

Remove the door panel using a trim removal tool to gain access to the window switch.
Disconnect the electrical connector from the window switch.
Test the switch with a multimeter for continuity. If defective, install a new switch by reversing the removal process.

4. Inspect and Replace Window Motor

If the switch is functioning, proceed to check the window motor.
Disconnect the window motor's electrical connector.
Apply direct power from a 12V source to the motor leads to see if it operates.
If the motor does not work, remove the window motor by unscrewing it from the window regulator.
Install the new motor by reversing the removal process, ensuring it is securely fastened.

5. Reassemble and Test

Reattach the door panel, ensuring all clips and screws are secured.
Reconnect the 12V battery.
Test the power windows to ensure proper functionality.
