I have operated the central locking many times to see if its just a 'stuck' actuator, that did not work.
On the subject of 'stuck' actuators; I have operated the central locking and gently hit the lock mechanism area hoping to free up any possible 'stuck' actuator, this did not work.
I have checked the fuses and they are OK, as its only one door that will not open and both rear doors are on the same fuse.
I have disconnected the inner door handle, so I can get to the cable to pull it a bit further, did not work.
I have operated the inner door handle twice in succession, this is what a lot of web sites say to do, did not work.
I have actuated both the inner and outer handles together, other web sites say do this, did not work.
I have taken the door card off the working side, to see if I can actuate the lock mechanism without using the central locking, i.e. mechanically actuate the locking mechanism, I can't find a way. If I could then I would go to the non working side cut off the door card, mechanically actuate the lock mechanism, open the door and then replace the lock mechanism and the actuator.
I'm am told on web sites that there is a way of actuating the lock mechanism without the door being open when the actuator in the lock mechanism is faulty but there are no instructions on how to do this.
any help please?
