I have a problem with the central locking on my 07 plate Galaxy. The rear near side door will not unlock and the child locks are active due to us having two young children. This means we can now not open the door. I have tried locking and unlocking over and over, pushing and pulling the door whilst trying to unlock, and also pulling out the internal lock whilst pulling the external door handle. Still no luck. There appears to be power getting to the lock as you can hear movement in the lock location, but nothing happens. The locking switch also jumps back in as soon as you pull it out and also tries to move when using the key fob suggesting something may be jammed but trying to work. I can not get the internal panel off as the screws are only accessable with the door in the open position.
Suspected the problem was not a common fault judging by the lack of response to the post, so the car went in to the main dealer. Got it back yesterday all fixed and as luck would have it, the door decided to open when they tried repeatedly locking/unlocking it(as had already tried myself with no success). Fault diagnosed as the solonoid in the switch mechanism so all replaced as it is one unit. (At least the door panel was left intact as the door could be opened to remove the screws properely) Anyway quite relieved as expected a very hefty bill but ended up just being the part cost and two hours labour. So overall good result, but disappointed with such a failure on a car just over 3 yrs old.
