Have been searching the forum for the answer to what appears to be same problem we have on one rear door on a 99 Clio
Door wont un-lock. Button tries to come up when you use the fob but just moves a bit. You also can't pull it up by hand un-like the door the other side. Its as though something is stopping the door un-locking.
Not being able to open the door I suppose the only option is to try and take the panel off with the door closed and see what is wrong.
Any clues on what it is as posts dont seem to conclude with the solution!
I have this precise problem on the rear door (driver's side) of my '00 Clio Grande 1.2. Was getting in with two other folk the other day and once the rear passenger was in the lock just stopped working. The knob jumps a bit when I use the central locking, so something is still happening, but the door won't open either from the outside or the inside
Wondering if this is going to be expensive...
