Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to prevent electrical shock.
Ensure the working environment is clear and safe.

Tools Required:

Multimeter
OBD-II scanner
Socket set
Screwdriver set
Wire stripper/crimping tool

2. Inspect and Replace Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Remove the power window fuse using a fuse puller.
Check the fuse for continuity using a multimeter.
Replace with the same amperage fuse if blown.

3. Test and Replace Window Switch

Remove the door panel to access the power window switch (use a screwdriver to remove screws and gently pry off the panel).
Disconnect the electrical connector from the switch.
Test the switch with a multimeter; if it does not show continuity when pressed, replace the switch.
Install the new switch by reversing the removal steps.

4. Inspect and Replace Window Motor

If the switch is functioning, access the window motor by removing the door panel and insulation.
Disconnect the window motor's electrical connector.
Test the motor by applying direct voltage from the battery.
If the motor does not operate, replace it by removing mounting screws and disconnecting it from the regulator.
Install the new motor and reconnect the electrical connector.

5. Reassemble Door Panel

Reattach any insulation removed during the inspection.
Reinstall the door panel by aligning clips and screws.
Ensure all controls are functioning before fully tightening screws.
