Solution

1. Preparation

Gather tools including a multimeter, socket set, screwdrivers, and replacement parts if necessary.
Disconnect the negative battery terminal to prevent electrical shock.

2. Check and Replace Fuses

Locate the fuse box, typically found under the dash or in the engine compartment.
Remove the power window fuse using a fuse puller or pliers.
Inspect the fuse for breaks or damage. Replace if needed with a fuse of the same amperage (check the owner's manual).
Reconnect the battery terminal after fuse replacement.

3. Inspect and Test the Window Switch

Remove the door panel to access the window switch.
Disconnect the switch connector and use a multimeter to test for voltage at the connector when the switch is pressed.
If no voltage is present, trace wiring back to the fuse box for faults; replace the switch if operational.

4. Test Window Motor

Disconnect the window motor from the window regulator.
Using jumper wires, connect the motor directly to the battery to check if it operates.
If the motor does not work, replace it with a new one.

5. Reassemble and Test

Reinstall the door panel carefully, ensuring all clips are secured.
Reconnect the battery and test the power windows for functionality.
