Hi all. Just got a good 2.6 1990 190E. Here is the scenario: All the central locking rods and boot locks work everytime when opening the car.
When closing the car most of the time but not always the rear sttriker rods don't go down properly so don't lock. It started on one door behind the driver's side, then sometimes both rear strikers, now even when I lock the doors from the passenger's side the door strikers on all doors except the one I'm locking don't go down.
I had a look through some previous posts about this. I checked the pump under the back seat with the seat removed and it was working ok with no long run on so I am presuming there are no holes in the airlines.
Does a pump get worn out on the vacuum cycle sometimes? It works ok on opening. Could the actuators or locks need oiled? Anybody had a similar problem and does anyone have any ideas on a fix. Please reply. Cheers.
