Ok, never owned or worked on 95 Golf before, so I have some questions regarding the rear hatch and hatch locking mechanism components please.
It does seem like an overly engineered and complicated locking / unlocking arrangement
First, how does the hatch lock and unlock? All of the moving components in the hatch were corroded and frozen, so I have freed them up with PB Blaster. Now they move. I can unlock the lock with the key, by pushing in the lock and turning the key CW. [ yes, clockwise IIRC ]. I cannot physically lock the lock with the key.........am I supposed to be able too?
The only way I can have the lock mechanism lock when the hatch is closed, is to physically pull that connecting rod from that electrical "box" to the passenger side before closing the hatch. I can hear the "gear noise" when I do this. I also hear that gear noise when I unlock the lock with the button inside the glove box. Yes, the lock does unlock [ now that I've lubed everything, it didn't used to ] with this button. Sorry, I don't know the correct name of the gear noise making box.
I see that there is a wire going to the lock cylinder. I also see a little button that sticks out on the bottom of the lock cylinder that makes contact with a small piece metal......as in a switch, when the key in the cylinder is rotated. Nothing happens when this lock cylinder switch is contacted. What *should* it do?
Lastly, there is that vacuum pump and the vacuum box with the plunger in it. The other 4 doors locks seem to "work" with this vacuum system. The locks are slow to go up, but go down fast with it. The rear hatch lock does nothing with the vacuum system. What "should" it be doing to the rear hatch lock, anything?
The vacuum pump runs for a long time when activated by the key in the drivers door lock.......like 30 seconds or a little longer before timing out.
If i knew how these components were supposed to work, I could figure out which is not, and change it out with a good used one from the wreckers.
Thanks for your thoughts.
