Solution

1. Preparation

Gather tools such as a multimeter, socket set, screwdrivers, and a replacement fuse.
Ensure the vehicle is turned off and the keys are removed from the ignition.

2. Check and Replace the Fuse

Locate the fuse box, which is typically under the dashboard or in the engine compartment.
Identify the power window fuse using the diagram on the fuse cover.
Remove the fuse using pliers and inspect it for continuity. If it is blown, replace it with a fuse of the same amperage rating.

3. Test the Master Switch

Remove the driver’s side door panel to access the master switch.
Disconnect the switch connector and use a multimeter to check for continuity between the terminals.
If the switch is faulty, replace it with a new one.

4. Inspect the Window Motor

Locate the window motor in the door panel.
Disconnect the motor's electrical connector.
Use a multimeter to check for voltage at the motor connector while pressing the window switch.
If there is voltage but the motor does not operate, replace the window motor.

5. Reassemble Door Panel

Reattach the door panel carefully, ensuring all clips and screws are secured.
Reconnect any electrical connectors that were disconnected during the repair.
