Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is off and remove the key from the ignition.
Disconnect the battery by removing the negative terminal.

2. Inspect and Replace Fuses

Locate the fuse box under the dashboard or in the engine compartment.
Remove the cover and locate the power window fuse as per the diagram.
Check the fuse; if blown, replace it with a new fuse of the same amperage.

3. Test and Replace the Window Switch

Remove the door panel 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 one.
Reinstall the door panel securely.

4. Test the Window Motor

Disconnect the window motor connector.
Using a multimeter, check for voltage at the connector when the switch is pressed.
If there is voltage but the motor does not operate, replace the window motor.
If no voltage is present, further inspect wiring leading to the motor.

5. Inspect Door Control Module

Access the door control module by removing the door panel.
Check for any visible damage or corrosion on the module.
If a fault is detected, replace the door control module and reprogram it if necessary.

6. Reassemble and Test

Reconnect all components and ensure that the door panel is securely fastened.
Reconnect the battery and perform a function test on all power windows.
