Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface with the ignition off.
Disconnect the battery to prevent any electrical shorts.

2. Check and Replace Fuses

Locate the fuse box, usually under the dashboard or in the engine compartment.
Identify the fuse for the power windows using the diagram on the fuse box cover.
Remove the fuse using a fuse puller or needle-nose pliers.
Inspect the fuse; if it is blown, replace it with a new fuse of the same amperage.

3. Inspect Window Control Switch

Remove the door panel using a socket set and pry tools to access the window control switch.
Disconnect the electrical connector from the switch and inspect for corrosion or damage.
If the switch is faulty, replace it with a new one.

4. Test Window Motors

If the switch is functioning, use a multimeter to check for voltage at the window motor connector when the switch is pressed.
If no voltage is detected, further investigate the wiring and connectors.
If voltage is present, remove the window motor and test it by applying direct battery power to see if it operates.

5. Reassemble Components

Once repairs or replacements are complete, reattach any connectors and the door panel.
Ensure all screws and clips are secured properly.
