Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative terminal of the battery to ensure safety while working on electrical components.

2. Inspect and Replace Fuses

Locate the fuse box as per the owner's manual.
Remove the power window fuse using a fuse puller.
Inspect the fuse and replace it if it appears blown (check filament).
Reinstall the fuse and reconnect the battery terminal.

3. Test and Replace Switches

Remove the door panel using a trim tool and socket set to access the window switch.
Disconnect the wiring harness from the switch.
Use a multimeter to test for continuity across the switch terminals.
Replace the switch if no continuity is detected by removing the old switch and installing a new one.

4. Assess and Replace Window Motor

If the switch is functional, check the window motor for operation.
Disconnect the window motor from the wiring harness and apply 12V directly from a battery.
If the motor does not operate, remove the motor by unscrewing it from the window regulator assembly.
Install a new window motor by reversing the removal steps and ensure all connections are secure.

5. Reassemble and Test

Reattach the door panel securely, ensuring all clips and screws are replaced.
Reconnect the negative battery terminal and test all windows for proper operation.
