Solution

1. Preparation

Tools Required: Socket set, multimeter, flathead screwdriver, trim removal tool.
Disconnect the negative terminal of the battery to ensure safety while working on electrical components.

2. Inspect and Replace Fuse

Locate the fuse box (typically under the dashboard or in the engine bay).
Remove the fuse for the power windows using a fuse puller or pliers.
Inspect the fuse for continuity. If blown, replace it with a fuse of the same amperage rating.

3. Check Window Switches

Remove the door panel using a trim removal tool and/or screwdriver.
Disconnect the window switch connector and test it with a multimeter for continuity.
If the switch is faulty, replace it with a new one.

4. Test Window Motor

With the door panel still removed, reconnect the window motor connector.
Apply voltage directly to the motor to see if it operates. If it does not work, replace the window motor.

5. Reassemble and Test

Reinstall the door panel, ensuring all clips and screws are secured properly.
Reconnect the negative battery terminal.
Test the rear windows using both driver and passenger controls.
