I have this "Information Display' on my 98,800 mlie 1996 car doing the same thing along with turning on/off the temp gage, volts light, tration control light, cruise control light and dinging the alarm constantly. I just got it back form the Olds dealer (they used to be one) and the GM mechanics diagnostics are the computer module for this display and other parts are not comunicating with the other modules in the car. Currently I have 3 modules dead and at $500 - $800 per module the car isn't worth the money. Good luck on yours.
