Hi All, I am new to the forum but hoping someone can help me. I have a 2012 T5 and purchased it a little over a month ago. I have the main switch set to come on when doors are open. Everything works okay with the exception of one thing. When the side door is shut and I lock the van the interior lights stay on. When I open the side door and lock the van the lights go off. I've tested all other doors and all works as it should so the problem lies with the side door. Can anyone help me understand. I've checked the cables in the door and everything looks correctly wired. The only other thing to add is the van has extra security locks on side and back door but not sure this would effect anything.
