Solution

1. Preparation

Gather necessary tools: socket set, multimeter, OBD-II scanner, and screwdrivers.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Inspect and Replace the Fuse

Locate the fuse box, typically situated under the dashboard or in the engine compartment.
Identify the power window fuse using the diagram on the fuse box cover.
Remove the fuse using a fuse puller or pliers and inspect for continuity.
If blown, replace it with a fuse of the same amperage.

3. Check and Replace the Window Switch

Remove the door panel using a screwdriver to access the switch.
Disconnect the wiring harness from the window switch.
Use a multimeter to test the switch for continuity. If faulty, replace with a new switch.
Reconnect the wiring harness and reassemble the door panel.

4. Inspect and Test the Window Motor

Access the window motor by removing the door panel.
Disconnect the motor wiring harness.
Use a multimeter to test for power at the motor connector when the switch is activated.
If there is power but the motor does not operate, replace the window motor.

5. Verify Window Regulator Functionality

If the motor is functioning but the window does not move, inspect the window regulator for mechanical failure.
Remove the regulator assembly if necessary and inspect for broken components.
Replace the window regulator if any issues are found.
