Hi everyone just new to the forum! I bought my Hyundai Trajet yesterday (private sale) and the only problem with it is that the light comes up for the doors being open even when they are closed. I think it's the passenger door causing this problem because when you press the central locking button that door doesn't lock you have to manually lock it with the switch inside or the key on that door out side. Any ideas where I can start? Thanks

 

There are switches on each door that tell the system if a door is open. Either a door is not fully closed, a switch is mis-aligned or the switch is bad.
