Solution

1. Preparation

Gather tools: multimeter, socket set, flathead screwdriver, and 12V power source.
Disconnect the battery terminal to ensure safety while working on electrical components.

2. Check and Replace Fuses

Locate the fuse box (usually under the dashboard or in the engine compartment).
Remove the fuse for the power windows using a fuse puller or pliers.
Inspect the fuse; if it is blown (the filament is broken), replace it with a new fuse of the same amperage.
Reconnect the battery and test the windows. If they still do not work, proceed to the next step.

3. Inspect Window Switches

Remove the window switch panel using a flathead screwdriver to gently pry it up.
Disconnect the wiring harness from the switch panel.
Using a multimeter, check for continuity across the switch terminals while pressing the switch.
If the switch is faulty, replace it with a new one.

4. Inspect Wiring Harness

Check the wiring harness connected to the window motors for any signs of fraying or breaks.
If damage is found, repair the wiring using electrical tape or replace the harness as necessary.

5. Test and Replace Window Motors

If the switches are functional, test the window motors by connecting them directly to a 12V power source.
If the motors do not operate, they will need to be replaced.
To replace, remove the door panel, disconnect the motor wiring, and unbolt the motor from the window regulator. Install the new motor in reverse order.
