Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to ensure safety during repairs.
Tools Required: Socket set, multimeter, OBD-II scanner, trim removal tools.

2. Inspect and Replace Fuses

Locate the fuse box; refer to the owner's manual for specific fuse locations.
Remove the power window fuse using a fuse puller or pliers.
Inspect the fuse visually; replace if blown with a fuse of the same amperage.
Reconnect the battery and test the window operation.

3. Test Window Switches

Remove the door panel using trim removal tools to access the window switch assembly.
Disconnect the window switch connector.
Use a multimeter to check for continuity at the switch terminals when pressed.
If the switch is faulty, replace it with a new unit.

4. Inspect and Test Window Motors

With the door panel removed, locate the window motor attached to the window regulator.
Disconnect the motor connector and test the motor directly with a 12V power source.
If the motor does not operate, replace it with a new motor.
Reassemble the door panel once repairs are completed.

5. Verify Control Module

If previous steps do not resolve the issue, the central control module may require replacement.
Locate the module, disconnect it, and check for any visible damage or corrosion.
Replace the module if necessary and reprogram it per manufacturer specifications.
