Solution

1. Preparation

Gather tools: multimeter, socket set, flathead screwdriver, and a trim removal tool.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Check and Replace the Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the power window fuse using the fuse diagram.
Remove the fuse using a fuse puller or pliers and inspect it for continuity.
If blown, replace it with a fuse of the same amperage.

3. Inspect and Test the Power Window Switch

Remove the door panel using a trim removal tool.
Disconnect the power window switch connector.
Use a multimeter to check for continuity between the switch terminals when pressed.
- If no continuity is detected, replace the switch.
Reconnect the switch once tested.

4. Test the Window Motors

Locate the window motor in the door.
Disconnect the motor from its electrical connector.
Use a multimeter to check for power at the connector when the switch is pressed.
- If power is present but the motor does not operate, replace the motor.
- If no power, check wiring and connections for damage.

5. Inspect Wiring and Connectors

Visually inspect the wiring harness between the door and the body for any signs of wear or damage.
Repair or replace any damaged wires or connectors.
Ensure all connections are secure.

6. Reassemble and Test

Reattach the door panel after all checks and repairs.
Reconnect the battery.
Test the power windows to ensure functionality.
