I have a Mercedes Benz S500 year 2000.
One day when I tried to turn on the cruise control, it did not work.
I tried all sorts of positions the cruise handle could go but it did
The display use to say Cruise Control on and the speed but it didnt say
One day i washed my car, and after that it worked again until I turned
the car off and went shopping. When I came back, it didnt work anymore
Does anyone have an idea of what may have happend?
