I think my 2000 4.6 is nominating itself for Marty's doorlatch test, when unlocked the locks go 'click-clack' and it happens more and more.

When driving I push the doorbutton to lock and then it stops (most of the time) so it's time to take action.

One other thing, there seems to be a weak link in the rod system, I have read a plastic connection that wears over time and can break and makes it inpossible to manually enter the EKA code when needed.

Before I pull everything apart I would like to know what part this is so I can order and replace it by way of precaution.
Any help appreciated.
Tony.

I haven't heard of one of the plastic clips on the latch breaking before... All of the latches I have pulled apart and repaired have had the clips intact.

But I believe that the part number you are mentioning is STC3881 for the RH front door, or STC3880 for the LH Front door. The fact that a quick google search I did on them shows a single clip being about £10 makes me think it isn't a commonly replaced item..

On all the ones I've actually replaced myself, I have never had one break either.

The weakest link (to my knowledge) in the locking/unlocking system is the metal tab that comes off the door lock barrel - people sometimes snap this when trying to release the rod from the spring clip there, and it's either a case of replacing the lock barrel or finding a way of reattaching/reinforcing the broken tab.

It does however sound like the CDL switch is somewhat intermittent/dodgy in your latch though!
