Thank you for the reply!
In fact my door cover is still off because I though somehow it could be the door lock actuator, so I wouldn't have to mount it and then unmount it again to replace the actuator. My next challenge is to find an actuator (I'm not sure if I can find any in the junkyard), but with a little bit of research I think I'll get one.
However, replace it is not the easiest thing to do because it's in a very tight location and I can't see what I'm doing, perhaps the best thing to do is to ask my mechanic to replace it.
I'll give it a try and then I'll give you feedback
