Hi all,
I have a problem (I think with the estate latch/locking mechanism YS4A 43102, like the one on this page http://www.karl.de/shopware.php/Stellmodul-Heckdeckel_detail_77058.html).

Sort story:
Is it possible to open it to see what is wrong and try to fix it? I cannot succeed, there is resistance that I cannot pin point (near the latch).

Long story:
One of my strut broke down and the trunk slammed down. I replace the strut and at that point, I realize that the trunk does not lock (it does not latch either). The weight on the trunk was keeping it down. It is no longer the case.
I have now remove the above mentioned part and try to open it. Now, I can lock it with a pliers, but pulling the rope (the estate model has a rope between the key cylinder) does not unlock it. I have to use the pliers to push the locking part and the arm move out and unlock.
Now I know that if I lock my trunk, it is over, I cannot unlock it (plus the part that I push with the pliers will not be accessible).
In any case I tried to plug the electric part to see if it was playing a role. With the electricity plugged in, when I pull the rope, the trunk light opens, but that is it.
The button on the dash to open the trunk never worked, so I cannot use it for diagnostic or else.

In summary:
I think I will have to replace that part, but my hope is that someone here can suggest me a trick to save the part that I currently have.

Happy new year!

Car: Ford focus estate (station wagon) sold in Sweden, so probably a European model.

That part is generally considered non-serviceable and is sold as a unit as you've found out. The locking latch mechanism is moved into place by an electric solenoid and it tends to wear out and bind with age; that is the latch or the solenoid or both wears out. I doubt something simple like a good regreasing would fix it. I also suspect any attempted fix would be temporary.

There are other threads on FF on how to service your trunk release button located on the dash.

Thanks for the quick and informative reply. I will buy a use part and try my luck.

Thanks for the info about the button on the dash. I will look for the solution.

Swap the part with one bought used. It works no problem.
