I know there are somewhat related threads about deadbolted doors but I'm still having some trouble figuring out what the problem is. The problem is with the passenger side rear door. Won't lock/unlock with any of the other doors or unlock manually. Tried to synchronize doors (didn't seem like the problem but was worth a shot..) to no avail. I can hear the actuators in all the other when a lock signal is sent by the keys in the front doors or moving the driver door. In this door however I feel/hear nothing. I can move the lock up and down somewhat and hear something in the door (but not the distinct locking or unlocking sound). Is this related to the deadlocking system? Thats what the lock seems to be doing. Don't know if this is related but since the second owner of the car (14 years ago) the trunk couldn't be locked/unlocked from the trunk lock cylinder. Someone in another thread mentioned the same thing but noone every said anything about it...

Also I know theres a procedure for removing the door panel without being able to open the door on bmwe34.net, but I still can't seem to get the panel off or find/disconnect the cable connected to the door handle...if that makes any sense.

Sorry that this is so long for such a small problem... and it may not make sense so feel free to question/criticize/anything.
