door lock

[Panama Jack]

cannot lock or unlock 1984 Carrera driver side door...with panel off I see that there is a rod running sideways to the locking wheel and then from there up to the lock button, but in mine the rod seems to be stuck...I'm having trouble seeing the mechanism on the inside of the door with flashlite and mirrors, and cannot find a diagram, so hard to figure out what's wrong in there. I don't want to take the whole window and rails out unless absolutely necessary. Any ideas or anybody with a diagram? thanks // Stew

Stew,

If you do not have a Bentley, these pictures might help.

Also, I'm not sure you can lock the driver's door while open.

Some one else will probably chime in.

Good luck,

Gerry

When I bought my 85 I had a similiar problem.
Make sure the circled tab is making contact with the rod plunger connected to the trigger.
I had to bend the circled tab so the trigger of the outside handle would push it in far enough to release the door from the outside.

thanks for pictures and suggestions...on mine, the trigger does contact the plate and the door will open and close...it's the lock that's the problem...in the picture, the rod I'm talking about that's stuck is the gold colored rod at the top right...I can't see what it's attached to down at the end where the mechanism is anchored to the door. The picture is similar to what I see with flashlite and mirror in that it's tough to see why the rod might be stuck. I do have the catch closed on the door itself as I'm also thinking the driver door will not lock if the catch is open...sorry not to have these terms down better...my appreciation for technical writers is increasing...next plan unless someone tells me different is to take apart the passenger door that works properly and see if I can find a clue or two...best // Stew

My 1975 us Carrera driver lock works if you manually do it from the passenger side with the door shut....the key won't lock the door though....same fix?

Is this picture correct?

[Panama Jack]

Yes, the labels on the picture are correct. Mine doesn't have the black tubing coming down from the mechanism. I have tried to force the "mechanism" downward with a screwdriver at about the point where the black tubing connects, but the "mechanism" doesn't want to move. Some other time you maybe can tell me how you make those cool red labels. Then I could've labelled the picture in the first place. Thanks much. // Stew

After taking the door panel off the properly working passenger door I see that the rod connects to a lever like piece that ultimately moves a plate at the very back of the door. When the plate rocks forward, the door is locked because the rocking motion disengages the effects of the whole trigger mechanism. I cannot see what's preventing the plate from rocking forward. I ordered the Bentley book to see if it might be of any help and because I will need it anyway sooner or later, and am thinking that the fix will come down to one of two possibilities: 1) take the rails out, remove the window, then pull the whole lock/opener and see what's gone wrong or 2) cut out a good part of the inside of the door with a metal saw so I can see what's wrong, fix it, then weld the sheet metal back the way it was. I'm favoring the second approach. You have to be slightly bonkers to be reading all this stuff, but I do it and see that a lot of others apparently do too, so still looking for suggestions. Strange, but it's encouraging to have others along on the trip. Best // Stew

2) is a bad idea. Too aggressive.

Let's see who else chimes in.

hi stew
had same sort of problems with my 1990 carrera 964 drivers side locking mech if yours is similar you can remove the whole unit without your drastic idea (2) and also non removal of the window mech. just remove the special type of screws near the striking arm on side of door and the relevant screws on the door panel remove the door handle and with wiggles and waggles the whole mechanism will come out, oh a bit of swearing helps but can be done without drastic actions messing up your door panel
sorry no pics but i managed without
good luck

Got the latch out of the door and thanks to those who advised against cutting the door frame. In the picture above my best guess is that there is a circlip missing from the shaft inside the spring pictured at the top. Getting another one and putting it on the shaft should solve part of the problem. The remaining issue has to do with the smaller spring at the left of the picture. It attaches to a plate (right side top of spring) that moves and basically blocks other important pieces from moving. I'm pretty sure that there is something missing from this plate, but there was nothing inside the door (it could have fallen out thru hole in botttom) and the pictures you guys have sent don't have this particular plate and spring at all. Neither does a sample lock that a Porsche mechanic (Tom Conway at Carquip) loaned me. I think everything would work if I just removed the spring and disabled the plate, but it has to be there for some reason, and two weeks ago there wasn't a problem with any of this. Any body see what's wrong here? Thanks // Stew

Fixed it! The solution involved putting on a new circlip and then realizing that the lock has two stages. The second stage wasn't engaging because it was crudded up. When it engages, the levered plate disengages and allows the other necessary parts to do things like lock/unlock. So I learned about the door lock and got a Bentley out of this deal plus learned that there are plenty of other goof balls out there around the clock thinking about their four wheeled friends and how to make them run right. Andale! // Stew

Whew! '74 914 drivers door. Exterior lock N/G. Everything else works?
