Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, flathead screwdriver, Phillips screwdriver, wire connectors.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Check and Replace Fuses

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Remove the cover and identify the power window fuse using the diagram on the fuse box cover.
Use a fuse puller or needle-nose pliers to remove the fuse.
Inspect the fuse; if it is blown (the filament is broken), replace it with a new fuse of the same amperage.

3. Test and Replace Window Switches

If the fuse is intact, remove the door panel using a flathead screwdriver and Phillips screwdriver to access the window switch.
Disconnect the window switch connector and use a multimeter to check for continuity.
If the switch is faulty, replace it with a new one and reassemble the door panel.

4. Inspect and Replace Window Motor/Regulator

If switches are functional, check the power window motor.
Remove the door panel to access the window motor and regulator assembly.
Disconnect the motor's electrical connector and use a multimeter to test for voltage when the switch is activated.
If no voltage is present, check the wiring for continuity. If voltage is present and the motor does not operate, replace the window motor/regulator assembly.

5. Reassemble and Test

After completing repairs, reassemble the door panel and reconnect any components.
Reconnect the vehicle battery, ensuring all connections are secure.
Test the power windows to ensure they are functioning correctly.
