Solution

1. Preparation

Gather necessary tools: multimeter, socket set, trim removal tools, and replacement parts.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Inspect and Replace the Fuse

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Identify the fuse associated with the power windows using the fuse diagram.
Remove the fuse using a fuse puller or pliers.
Check for continuity using a multimeter; if blown, replace it with a new fuse of the same amperage.

3. Test and Replace the Window Switch

Remove the door panel using trim removal tools to access the window switch.
Disconnect the switch connector and test for continuity using a multimeter.
If the switch is faulty, replace it with a new switch.
Reconnect the switch and reassemble the door panel.

4. Inspect and Replace Window Regulators (if necessary)

If the switch is functional, proceed to inspect the window regulator.
Remove the door panel completely to access the window regulator assembly.
Disconnect the window motor connector and test it with a multimeter for power.
If the motor is defective, remove the window regulator by unscrewing the mounting bolts and disconnecting it from the window.
Install the new window regulator by reversing the removal steps, ensuring the window is aligned properly.

5. Reassemble and Reconnect

Reinstall the door panel securely, ensuring all clips and screws are in place.
Reconnect the vehicle battery and test the power windows for functionality.
