Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to prevent electrical shock.
Ensure the work area is clean and well-lit.

2. Check and Replace Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Remove the fuse for the power windows (check owner's manual for specific location).
Inspect the fuse for continuity; replace it if blown with the same amperage rating.

3. Inspect and Replace Window Switch

Remove the door panel using a socket set to access the window switch.
Disconnect the electrical connector from the switch.
Test the switch with a multimeter for continuity when pressed.
If faulty, replace the switch with a new one and reconnect it.

4. Test and Replace Window Motor

Remove the door panel to access the window motor.
Disconnect the electrical connector from the motor.
Use a multimeter to check for voltage at the motor connector when the switch is activated.
If there is voltage but the motor does not operate, replace the window motor.

5. Reassemble Door Panel

Carefully reattach the door panel, ensuring all clips and screws are secured.
Reconnect the battery.
