Solution

1. Preparation

Gather tools and ensure the vehicle is parked safely.
Disconnect the battery to prevent electrical shorts during repairs.

Tools Required:

OBD-II scanner
Multimeter
Socket set
Screwdriver set
Wire crimping tool
Electrical tape

2. Inspect and Replace Fuse

Locate the fuse box, typically under the dashboard or in the engine compartment.
Identify the power window fuse using the diagram on the fuse box cover.
Remove the fuse using a fuse puller or needle-nose pliers.
Inspect the fuse for a break in the filament. If blown, replace it with a new fuse of the same amperage.

3. Test and Replace Power Window Switch

Remove the switch panel by gently prying it up with a flathead screwdriver.
Disconnect the switch connector.
Use a multimeter to test for continuity across the switch terminals when pressed.
If there is no continuity, replace the switch with a new one.

4. Inspect Wiring Harness

Trace the wiring harness from the switch to the window motor.
Look for signs of wear, fraying, or corrosion in the connectors.
Repair any damaged wires using a wire crimping tool and electrical tape to secure connections.

5. Test and Replace Window Motor

Remove the door panel to access the window motor.
Disconnect the motor's electrical connector.
Apply direct battery power to the motor terminals to check if it operates.
If the motor does not work, remove it and replace it with a new motor.

6. Reassemble Components

Reattach the door panel, ensuring all clips and screws are secure.
Reconnect the battery and test the window operation.
