Solution

1. Preparation

Gather tools: socket set, screwdriver set, multimeter, and trim removal tools.
Disconnect the vehicle battery to ensure safety while working on electrical systems.

2. Check and Replace Fuse

Locate the fuse box (typically found under the dashboard or in the engine compartment).
Identify the power window fuse using the fuse box diagram.
Pull the fuse using a fuse puller or pliers and inspect it for continuity.
If blown, replace it with a new fuse of the same amperage (usually 30A).

3. Inspect Window Switches

Remove the door panel using trim removal tools and screws.
Disconnect the window switch connector.
Test the switch with a multimeter to check for continuity when pressed.
If the switch is faulty, replace it with a new switch.

4. Test Window Motor and Regulator

With the door panel removed, access the window motor and regulator.
Use a multimeter to test the voltage at the motor connector while pressing the window switch.
If there is voltage but the motor does not operate, replace the window motor.
If there is no voltage, trace the wiring back to the switch for breaks or shorts.

5. Reassemble and Test

Reconnect all connectors, ensuring they are secure.
Reinstall the door panel and screws.
Reconnect the battery and test the power windows to confirm proper operation.
