Gather tools and parts needed for the repair.
Ensure the vehicle is parked in a safe location, and the ignition is off.

Remove the screws securing the touch screen assembly using a Torx screwdriver (usually T20).
Gently pull the touch screen away from the dashboard to access the connectors at the rear.

4. Inspect and Reconnect Wiring

Check the connectors for any visible damage or corrosion.
Disconnect and then reconnect the wiring harnesses to ensure a secure connection.
If any wires are damaged, replace them with new wiring.

5. Test the Touch Screen

Reconnect the 12V battery and power on the vehicle.
Check if the touch screen is responding properly to input.
If the issue persists, consider replacing the touch screen assembly.
