Solution

1. Preparation

Gather necessary tools: multimeter, fuse puller, flat-head screwdriver, socket set.
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).
Remove the power window fuse using a fuse puller.
Inspect the fuse; if it is blown, replace it with a new fuse of the same amperage (typically 30A).

3. Test the Power Window Switch

Remove the switch panel using a flat-head screwdriver to pry it up gently.
Disconnect the wiring harness from the switch.
Use a multimeter to test the switch for continuity. If there is no continuity when the switch is pressed, replace the switch.

4. Inspect Wiring and Connections

Visually inspect the wiring harness for fraying or damage, especially where it enters the door.
Ensure all connectors are securely attached and free from corrosion.

5. Test the Window Motor

If previous steps do not resolve the issue, remove the door panel using a socket set to access the window motor.
Disconnect the motor’s wiring harness.
Use jumper wires to connect the motor to the vehicle battery directly. If the motor operates, it may need to be replaced.

6. Reassemble Components

If repairs or replacements were made, reassemble the door panel and switch panel.
Reconnect the vehicle battery.
