door lock innards - help needed

[krasuskyp]

Hoping someones here w/ inner door lock workings knowledge can help me finish sorting my driver's door lock.

The tumbler pulled out w/ the key, had been spinning in handle (but working) for a year, then stopped working, then pulled out.

Tore door panel down, found all the bits.

The failure mode appears to be the screw which retains this whole mess to the back of the tumbler loosened then eventually pulled the top few threads out. I had to use a longer slightly thicker thread to get it to hold, but all's good there.

once handle's off, latch mechanism reassembly would seem to only go one way as most of it is keyed and obvious, with exception of how 'this' is clocked:



Anyone got a pic of how the clocking of those 2 zinc coated arm pieces are supposed to fit together? The bottom one (spring retainer) can only go one way as the spring ears once inserted then key into the plastic tumbler barrel bore. But the top zinc arm is 'geared' with the bottom one, at their midpoint where that little boss is seen. Can clock the arm more CCW a couple mm's...

more pics of this:






I thought I had it right, but turning the key only unlocks that door (manually), once that lock is up the passenger one trips open... but then the key does not engage anything from there... no lock no unlock (until you lock the car again from other side and repeat process.



So my question is - how is this area supposed to interact? Meaning, the tumbler's lock 'arm' (lever on the left in ^pic^) to the door lock's lock 'arm' (appears with grey coated tip on right in ^pic^).

When you turn the key CCW to unlock, the left lever comes down and interacts with the grey tipped lever on the right. The grey tipped lever cannot be manipulated by hand nor the lock knob, only moves w/ the lock button.

Thoughts on where I went wrong here?

TIA, all...

shoot, no one here has any insight / experience to share on this?

I would appreciate any suggestions - thanks gents

If I didn't currently have the car apart for another task, I'd see if I could look inside mine and offer any insight.

You might try spending more time on the forum search.

You have central locking where your key only unlocks the door mechanically. The door will only lock electronically by key or mechanically inside the car with the door closed. My guess would be that you don't have the central lock plugged in right or that there is a small plastic "roller cam" that goes on the barrel shaft that I think actuates the central lock. Try locking the car from the passenger side with the key. If it doesn't lock, you have a problem with your central locking.

Hope this helps.

BTW, You didn't do anything wrong. Central lock mechanisms only have one "ear" to unlock the door. As I said above, they lock electronically with an actuator attached to the latch system.

thanks guys

I have tried searching but no luck yet

the locks work fine from passenger door with key, from passenger door with knob inside, from center console button, but not with driver's key...

driver's key manually unlocks the driver's door first, then triggers the central unlock, but that's only a 1-time shot... then that key is disengaged and does nothing until you lock the car elsewhere and start again

I really could use a good picture of how this piece is clocked:



and a good picture of how that piece interfaces with the grey tipped arm to the right:



again, thanks for any help here!

Heres a pic off another thread. I had they same issue you are having.

[krasuskyp]

^thanks!!!^

crap - looks like I have mine on right?

if you had same issue, any thoughts as to what I'm doing wrong here?

maybe I'm not clocked enough toward the latch?

My problems started with a cylinder that would turn in the lock without doing anything( i.e. locking unlocking) sometimes it would engage but at first I didnīt pay enough attention(stupid me). One day the cylinder came out and I relaized the screw which held everything in place had fallen off and hence I could pull the cylinder. Pulled the door apart and sure enough the srew was gone so I gat a replacement. Put it back together and it still wouldīnt lock. I tried locking it and it kept unlocking itself as if one of the doors was still open. Went to a friend who has a porsche workshop and he sugested trying to switch the micro switch ( that tiny white cable going over the back of the lock. I donīt know if it was failing or I had damaged mine pulling the lock( they are very sensitive) but sure enough we swapped the micro switch and everything worked again. It sounds like you have the same problem I did. The microswitch is overiding the mechanics and stopping you from locking the door. Before I pulled the lock(drivers side) I could lock it from the poassenger side or using the central console but with time the whole system collapsed. I should have probably repalced the screw as soon as I noticed something wrong than waiting for the micro switch to fail as well! You live and learn

excellent details, thank you for sharing your experience

exactly what I've got going on it sounds

hey, least yer in good company on the "not smart enough to address it promptly" approach 8-) d'oh.

any idea where said micro switch resides? Is it pictured in any of what's been posted here?

You posted a pic of the micro switch in your first post I believe. Look at the small gray wire that runs up to the body of the door handle. That's your micro switch.

Look up Central locking problems for more help but my bet is you have a bad micro switch.

The 4th pic down in your first post, the piece with the 703 number on it. That's your micro switch.

The interesting thing to me is that your passenger side will lock both sides. I was under the impression that if one micro switch went bad, neither side would work because it took both sides "communicating" to make the system work right.
