Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Inspect and Replace Fuse

Locate the fuse box under the dashboard or hood.
Remove the power window fuse using a fuse puller.
Inspect the fuse for continuity; replace if blown with a fuse of the same amperage (typically 30A).

3. Replace Power Window Switch

Remove the door panel to access the power window switch:
- Use a screwdriver to remove screws securing the panel.
- Carefully pry off the panel using a trim removal tool.
Disconnect the switch connector.
Replace with a new power window switch by reversing the removal steps.

4. Test and Replace Window Motor

If the switch replacement does not resolve the issue, proceed to test the window motor:
- Remove the door panel as previously described.
- Disconnect the window motor connector.
- Use jumper wires to connect the motor directly to the battery.
- If the motor does not operate, replace it with a new one.

5. Reassemble Door Panel

Once repairs are complete, reconnect all components.
Align the door panel and secure it with screws.
Test the power windows again before replacing any clips or covers.
