Hi, I just bought a 1995 405 td estate at the weekend. The back passenger side door doesn't lock with the remote central locking, but unlocks fine. The push pin can be pushed down to lock the car but feels a bit stiff, and it doesn't click open or closed in a very positive way (Compared to my old Mercedes the whole car doesn't feel very positive, but thats a different matter!)
Before I pull the door card off are there some common problems I should look for? Can i lubricate the mechanism without taking the door card off? I read somewhere that the actuator has a worm gear that can jump, would I just force it back? Am i right in saying that its a positive 12v pulse to move the lock one way and a negative the other?
Can i disable the locking on this door somehow, ie pull a wire out somewhere?
Any insights would be much appreciated, Thanks
