Not sure if this is really a problem, but here goes. In my 1996 D1, when i lock my driver's side door, all the other locks close as they should, but there is a small delay in the right rear passenger door lock. I hear them all lock, but the right rear passenger lock goes down just a fraction of a second or so later, as if it is on some type of delay. It has been doing this for a long time, but is there some impending breakdown looming in the future? Is there anything I should do at this point or just let it be and see what happens? Thanks.
