Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety while working on the electrical system.

2. Inspect and Replace Fuses

Locate the fuse box, typically under the dashboard or in the engine compartment.
Identify the fuse for the power windows using the fuse diagram.
Remove the fuse and inspect it; if blown, replace it with a new fuse of the same amperage.

3. Test and Replace Window Switches

Remove the door panel using a trim tool to access the window switch.
Disconnect the window switch connector and use a multimeter to check for continuity when the switch is pressed.
If faulty, replace the window switch with a new one and reconnect.

4. Test and Replace Window Motor

If the switch is functional, remove the door panel and locate the window motor.
Disconnect the motor's electrical connector and test for voltage when the switch is activated.
If no voltage is present, further diagnose the wiring; if voltage is present but the motor does not operate, replace the window motor.

5. Inspect Wiring Harness

Trace the wiring harness from the switch to the motor, checking for any damaged insulation or broken wires.
Repair any damaged wiring with electrical tape or by replacing the affected section.

6. Reassemble Components

Reattach the window motor and ensure it is secured properly.
Reinstall the door panel and ensure all clips and screws are fastened.
Reconnect the negative battery terminal.
