We've been having trouble with the passenger power sliding door not completely closing and therefore not locking with the key fob. It will lock manually on the door lock. However we don't always remember to lock it manually and were afraid it could lead to a breakin. Once in a great while, it will lock with the don, but not often at all. I checked for obstruction in the track, and it was clear. I also cleaned the contacts( no idea, just thought is try it) do I possibly have a bad wire in the door, or a lock mechanism going bad? Any and all ideas would be appreciated. Thank you.
