My dash just started messing up. 1989 535i 214,000miles auto. Speedo bounces, no fuel gauge response, when lights are on, the odometer, and trip flicker, and when adjusting the dimmer switch the speedo bounces, and did I mention no more cluster lights at night. All worked 3 days ago off and on. What is the difference between the white, and the blue casing, besides the color? The prduction Date?
Any help would be great.
