Can anyone enlighten me as to what this switch does ? It looks like a upside down van ! There is nothing in the Mercedes hand book and when pressing in daylight nothing happens but doing the same at night there was a crack and the instrument panel light fused ! (not trying that again) Is it something carried over from a Sprinter Van ?
