Solution

1. Preparation

Gather necessary tools: multimeter, OBD-II scanner, fuse puller, and basic hand tools.
Disconnect the battery to ensure safety while working on electrical components.

2. Check and Replace Power Window Fuse

Locate the fuse box (usually under the dashboard or in the engine bay).
Identify the fuse related to the power windows by referring to the fuse diagram.
Remove the fuse with a fuse puller and inspect it for damage.
If blown, replace it with a new fuse of the same amperage.

3. Test and Replace Window Switch

Remove the panel covering the window switch using a trim removal tool.
Disconnect the switch connector and use a multimeter to test for continuity.
If the switch is faulty, replace it with a new one by reversing the removal process.

4. Inspect Wiring and Connections

Visually inspect the wiring harness connected to the window motor for frays or cuts.
Check the connections for corrosion or looseness.
Repair or replace any damaged wires or connectors as necessary.

5. Test and Replace Window Motor (if necessary)

If the switch and wiring are functional, test the window motor by applying direct power from a 12V battery.
If the motor does not operate, remove it from the door panel.
Replace it with a new motor by following the manufacturer's instructions for installation.
