To fix the touch screen on your 1989 Buick Riviera, first check the connections behind the screen for any loose or damaged wires. If the screen is unresponsive, try resetting the system by disconnecting the battery for a few minutes and reconnecting it. If issues persist, consider replacing the touch screen or seeking professional help, as older models may have specific compatibility concerns. Additionally, you may want to consult a repair manual for detailed troubleshooting steps.
