Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, basic hand tools (screwdrivers, trim removal tools).
Disconnect the vehicle's power supply to ensure safety while working on electrical components.

2. Inspect and Replace Fuses

Locate the fuse box (usually beneath the dashboard or in the trunk).
Identify the fuse associated with the power windows (refer to the owner's manual).
Use a multimeter to check for continuity in the fuse. If blown, replace it with a fuse of the same amperage.
- Sub-steps:
  - Remove the fuse using a fuse puller or pliers.
  - Insert a new fuse into the same slot.

3. Examine Window Switches

Remove the door panel using trim removal tools carefully to avoid damage.
Disconnect the window switch harness and inspect for corrosion or damage.
Test the switch for continuity using a multimeter. Replace if faulty.
- Sub-steps:
  - Pull off the switch from the door panel.
  - Use a multimeter to check for proper function and replace if necessary.

4. Check Window Motor Functionality

With the door panel removed, locate the window motor.
Disconnect the motor's electrical connector and use a multimeter to check for power supply when the switch is activated.
If no power is present, further investigate wiring or control modules.
If power is present, replace the window motor.
- Sub-steps:
  - Remove any screws or fasteners holding the motor in place.
  - Install the new motor and reassemble the door panel.

5. Reset Window Controls

Reconnect the vehicle’s power and reset the window control system.
Use the touchscreen to perform a window recalibration if necessary, following manufacturer instructions.
