1997 Buick Park Avenue Question: car was idling,headlights started going off and dash lights brighten. what's up?
Would suggest have your alternator tested - sounds like the regulator is having a bad day. Overcharging the electrical system. - ProfessorG
Have the headlight switch and the wire connector to the switch checked for signs of arcing (blackened terminals) or melted plastic. - pushrod
