Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety during the repair.

2. Inspect and Replace Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the power window fuse using the diagram on the fuse box cover.
Use a fuse puller to remove the fuse and check for continuity using a multimeter.
- If blown, replace with a new fuse of the same amperage.

3. Test Window Switches

Remove the door panel using a trim removal tool to access the window switch wiring.
Disconnect the switch harness and use a multimeter to test for voltage when the switch is activated.
- If no voltage is present, replace the switch.

4. Inspect Window Regulators

With the door panel removed, check the window regulator for any signs of damage or obstructions.
If the regulator is faulty, remove it by:
- Detaching the window from the regulator.
- Unscrewing the regulator from the door.
- Installing a new window regulator in reverse order.

5. Reassemble and Test

Reinstall the door panel, ensuring all clips are secured.
Reconnect the negative battery terminal.
Test each power window to ensure proper functionality.
