One problem related to dashboard failed has been reported for the 1998 Buick Regal. The most recently reported issues are listed below.
This vehicle appears to have a serious electrical problem. The problem started with the left blinker going really fast when depressed (as if going out). Then every time you depress the left blinker the electrical on the dash goes off and blinks. The engine shuts off and the steering wheel locks up while driving. Luckily everytime it has happened we have not been in an accident, but this could seriously put someone in danger. I don't know if it is related but the electrical on the thermostat control dashboard has gone out as well as some of the electrical on the windows.
