My closing assist on the hatchback of my 87 300DTD has suddenly and without warning quit working. I have done a search on the archives with not much help available and I have checked the fuse--it is new and good and my central locking systems works so I would think the vacuum part of the assist is good--I can hear and see the hatch lock close by vacuum --so I am not sure where to go from here. Any suggestions? I don't find the electric motor offered by fastlane
TIA
