Solution

1. Preparation

Gather tools and necessary parts.
Disconnect the vehicle battery to ensure safety during repairs.

Tools Required:

Multimeter
OBD-II scanner
Socket set
Screwdriver set
Trim removal tool

2. Inspect and Replace the Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Identify the power window fuse using the diagram on the fuse box cover.
Remove the fuse and check if it is blown; replace with a new fuse of the same amperage if necessary.

3. Test and Replace the Window Switch

Remove the door panel using a trim removal tool and screws.
Disconnect the window switch connector and test for continuity.
If the switch is faulty, replace it with a new one.
Reconnect the door panel once the switch is replaced.

4. Inspect and Replace the Window Motor

If the switch tests are okay, remove the door panel completely.
Disconnect the window motor connector and check for voltage when the switch is activated.
If no voltage is detected, trace wiring back to the switch or fuse.
If voltage is present but the motor does not work, remove the window motor from the door assembly and replace it.

5. Reassembly

Reinstall the door panel, ensuring all clips and screws are secured.
Reconnect the vehicle battery.
Test the power windows to ensure they are functioning correctly.
