My son drives an 89 SC with about 105 k on the ODO. Recently, his brake stopped working properly, they act as though they lost their power assist. At the same time, his guages stopped working and his AC / heater control stopped working. We are thinking that a computer has gone out, but are unsure where to start with any troubleshooting. Could any of you help us to get the repair of these problems repaired? Thanks to all who reply!!!!!! SICK COUPE IN INDY
