I have a1989 190e mercedes 2litre that i found had the vacume pump for the centre locking missing,i replaced this and still the centre locking does not work.When i activate the door locks the vac pump buzzes for about
30seconds but the centre locking does not operate.Has anyone got any suggestions including how to test to find a solution to getting the centre locking to work again?many thanks- posted
