Solution

1. Preparation

Gather tools such as a multimeter, socket set, flathead screwdriver, and a fuse puller.
Ensure the vehicle is parked, and the ignition is turned off.

2. Check and Replace Fuse

Locate the fuse box (typically under the dashboard or in the engine compartment).
Identify the power window fuse using the fuse diagram.
Use a fuse puller to remove the fuse and visually inspect it for breakage.
If blown, replace it with a new fuse of the same amperage rating.

3. Inspect Window Switches

Remove the door panel using a flathead screwdriver to carefully pry off any clips.
Disconnect the battery before proceeding to avoid electrical shock.
Inspect the power window switch for any signs of physical damage or corrosion.
Clean contacts if necessary; otherwise, replace the switch if damaged.

4. Test Window Motor

Disconnect the window motor from its wiring harness.
Use a multimeter to check for power at the motor connector when the switch is activated.
If no power is detected, trace back to the switch or wiring for faults.
If power is present but the motor does not operate, replace the window motor.

5. Reassemble Components

Reattach the door panel securely, ensuring all clips and screws are in place.
Reconnect the battery and test all windows to verify functionality.
