Self Locking Doors...

[rovermud]

This is not a feature I expected but get. My doors on my D1 will lock by themselves...wth the keys inside of course :sly:. I have narrowed it down to a little sensor/button or somthing inside the driver door just underneath the door lock pull tab thingy...but it's inside the door frame. It's appears to have brokekn free from the door frame. I don't know what it's called so I have no way of ordering it. Any ideas?

Thanks
Patrick
