Oldsmobile/Buick Repair: RIVIERA CODES, buick service, buick riviera

Question
MY 89 BUICK RIVIERA IS SHOWING A CODE # 26, ACCORDING TO MY BOOK THAT IS A "QUAD DRIVER CIRCUIT" CAN YOU TELL ME WHAT THAT CONSIST OF? HOW DO I FIX? ALSO, THIS RIVIERA HAS A TOUCH SCREEN THAT CONTROLS RADIO, GAUGES, AC/HEATER, AND HAS A DIAGNOSTIC SCREEN. I WAS TOLD THAT YOU COULD RETRIEVE OTHER CODES BY PUSHING A SERIES OF BUTTONS ON THE SCREEN, ARE YOU AWARE OF HOW THAT IS DONE? ANY HELP ON THESE TWO TOPICS WOULD BE APRECIATED!, THANKS

Answer
Unfortunately I do not posess a 1989 Buick service manual in order to retrieve the information from. You will need to access an original service manual for the information.

Do NOT buy a CHILTONS or HAYNES manual or other GENERIC book as they do NOT have the detailed information that you need in these books.
