Hi Peter, OK - changed the brake light bulbs for new ones - coated them with contact lube - now the CC drops in &out.
So, next I guess I need to look at the AMP solder joints? Last I looked at the MB circuit boards the solder joints were pretty small. But I'll try - better than spending $450 or more. I prefer to buy new electronics - haven't had good luck with used. Who can check the servo? How is it done? MB dealer?
