Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the battery to prevent any electrical shorts.

2. Check and Replace Fuse

Locate the fuse box (usually under the dashboard on the driver's side).
Identify the fuse for the power windows using the diagram on the fuse box cover.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse; if blown, replace it with a new fuse of the same amperage.

3. Inspect and Replace Window Switch

Remove the door panel using a screwdriver and trim removal tool.
Disconnect the window switch connector.
Use a multimeter to test for continuity across the switch terminals.
If the switch is faulty, replace it with a new switch and reconnect.

4. Examine Wiring and Connections

Inspect the wiring harness for any visible signs of wear, fraying, or disconnections.
Repair any damaged wires using electrical tape or replace sections as needed.
Ensure all connectors are securely plugged in.

5. Test and Replace Window Motor (if necessary)

Disconnect the window motor from the regulator.
Use jumper wires to connect the motor directly to the battery to test its operation.
If the motor does not operate, replace it with a new motor.
Reinstall the motor and connect it to the regulator.

6. Reassemble Door Panel

Carefully reattach the door panel, ensuring all clips and screws are secure.
Reconnect the vehicle's battery.
