Solution

1. Preparation

Gather tools: socket set, multimeter, screwdriver set, and wire connectors.
Disconnect the vehicle's battery to ensure safety while working on the electrical system.

2. Inspect and Replace Fuse

Locate the fuse box, typically found under the dashboard or in the engine bay.
Remove the cover and identify the power window fuse using the diagram on the cover or the owner's manual.
Pull the fuse out using fuse pullers or pliers; check if the metal strip inside is broken.
If blown, replace with a new fuse of the same amperage.

3. Test and Replace Window Switch

Remove the door panel using a screwdriver to access the power window switch.
Disconnect the wiring harness from the switch.
Use a multimeter to check for continuity through the switch.
If the switch is faulty, replace it with a new one and reconnect the wiring.

4. Inspect and Replace Window Motor

If the switch is functional, check the window motor.
Disconnect the wiring harness from the motor.
Test the motor directly by applying 12V from a battery; listen for any noise.
If it does not operate, remove the motor from the regulator by unscrewing it.
Install a new motor by reversing the removal steps, ensuring it is securely fixed.

5. Reassemble Door Panel

Carefully replace the door panel by aligning it with the clips and screws.
Reconnect the battery.
Test the power window operation before finalizing the assembly.
