Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and screwdriver.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Inspect and Replace the Fuse

Locate the fuse box (usually under the dashboard on the driver's side).
Remove the cover and identify the power window fuse using the diagram on the fuse box cover.
Use a fuse puller or needle-nose pliers to remove the fuse.
Inspect the fuse for continuity; replace it with a new fuse of the same amperage if blown.
Reinstall the fuse box cover.

3. Test and Replace the Window Switch

Remove the window switch panel using a flat screwdriver to gently pry it upwards.
Disconnect the electrical connector from the switch.
Set the multimeter to continuity mode and test the switch terminals.
If the switch is faulty, replace it with a new switch by reconnecting the new switch and securing it back into the panel.

4. Check and Replace the Window Motor

Remove the door panel using a socket set to unscrew any bolts and a flat screwdriver for clips.
Disconnect the electrical connector from the window motor.
Use the multimeter to check for voltage at the connector when the switch is pressed.
If there is voltage but the motor does not operate, remove the motor by unscrewing it from the regulator and replace it with a new motor.

5. Reassemble

Reattach the door panel securely, ensuring all clips and screws are fastened.
Reconnect the negative battery terminal.
