An odd elctrical problen popped up on my '98 Buick regal GS yesterday. Driving down the road I turned on my right blinker to make a turn and the dashboard warning lights for the break and air bags began to blink. Later I turned on the left blinker and the tach and speedometer began to sweep back and forth and all of the warning lights on the dash began to blink. Seems to be an intermittent problem that comes and goes. I was wondering if this is an indication of the Body Contrl Modual going bad.
