During my repaint I had the driver door lock rekeyed to match my other keys. My paint guy installed it but it's not right. It's in the door, the key turns both directions, but the door doesn't change it's lock status and the post doesn't go up or down.

I'd like to correct this before I put the door panels back on. Does anyone have a door lock howto or other advice about what got messed up?

Paint guy installed the lock ?
Likely connecting rod (49) or operating rod (50) not attached - ball and cup - see diagram.

Yup, getting that little ball and socket back together in there is a b!tch if you have regular sized hands. I had to use a long screwdriver to pop it back on. Also, since it's plastic it might be worn or broken.

There is also a failure mode of the lock cylinder assembly itself where the little ball or the ring it's mounted on can crack since it's just made of cheap pot metal. Since your lock cylinder didn't match the rest of the keys this probably started the whole thing but presumably the new one is good.

I could not push mine of with a screwdriver but manage to use an angle set up needle nose pliers.. I found it much easier as you are not pushing on the other side of the arm..

This does require nimble finger/tool work. However, it is easier to join them than it is to separate the joint.

Looks like it's 50, just dangling free from the lock. Can't really see what it attaches to or how it's secured. Really tight in there.

bronto

OK, I figured it out by studying the passenger side. So now it's connected. Just snap on to secure it? Doesn't seem to be anything else.

Drove my car to work today for the first time since mid-October Yay, nice to be back in the saddle.

I need to revisit a question I asked early in my restoration process, something I wanted to fix when it was down, but the door panels are still off so it's not too late...

My door locks aren't completely in sync when using the key. Locking the driver side door often locks the passenger side door, but not always. Unlocking from the driver side does NOT unlock the passenger side. Locking/unlocking the passenger side door ONLY affects the passenger side door.

When I bought the car in 2006, they worked perfectly. However the passenger window guide needed repair, and when I got it back from the mechanic they were like this.

When I started restoration, it was suggested that maybe the time piece on the door lock was screwed on too tight, which made perfect sense and I considered the matter solved, in theory. The door was already apart so I couldn't test. But the problem is still there, and the trim isn't even on the door yet.

Other suggestions?

Remember, this is a '79. Vacuum operated locks.

Hey there.
I had an issue with each door lock. First, only locking/unlocking passenger side would result in synchronous action of the door locks. Driver's side would lock/unlock normally, but not communicate with the passenger side. The problem for this I found was a frayed, then split, ground wire on the driver's side in the bundle at the 'stress point' where the wires are in that black tube. The second issue giving me non-synchronous lock action was after I tightened up the passenger side inner door handle apparently to much. Note this was after it had functioned normally. The locking and tightening nuts are at the fore end of shaft (41) where it seats with the inner door handle.
These could be things you could inspect first.
I am not familiar with the earlier models vacuum system, so maybe another can chime in on this.
Best Wishes

Yeah so the ground wire wouldn't be an issue with mine, since it's not electric. But the same principal would mean to make sure the vacuum lines are tightly sealed.

Seems strange that the door handle could cause a problem, but it's probably the same on a vacuum system so I will look at that.

bronto

Well I don't think that's it. I loosened up the nuts completely and there was no change. With the help of a friend, I have verified that the "plunger" on the passenger side moves well - a large distance - when the driver side lock is turned. It just doesn't seem to DO anything.

Mike Frye

When you say it just doesn't seem to DO anything, what do you mean?

And what is a 'large distance'?

Can you tell what is supposed to be happening? If you use your hand in there can you actuate it so that it does lock/unlock?

It sounds like something else may have been popped off at the time the work was done and was never put back together.

bronto

I can see inside the door and see that the servo/actuator/whatever it's called is extending or retracting about an inch; should be enough in my estimation to raise or lower the door lock post.

I can see that it is traveling inside a slot, but there isn't anything else in that slot that it is effecting. SO yeah, maybe something popped off. Not sure what to look for. I have looked at some diagrams but haven't seen anything on them that looks like my car.

bronto

OK, this is much easier at night when the sun and sky isn't in the background.



You can see (I hope) a broken fastener of some sort hanging off the rod at the top of the photo. Those are two pieces, and they just dangle there. I can't really see what the fastener on the end of the lower rod looks like, but I imagine it's the same. A clip of some sort.

Anybody know what these are, are called, where they can be had? I hope to not need another order from 928 Int. at this point.
