I have 99 Explorer. All doors locked automatically when I shift gear to drive. It is not doing so now and I have to lock or open doors manually. I do not have the manual book. I suspect maybe the fuse is blown. Two fuse boxes - one in the hood, the other on dash board by driver side. I do not know the right fuse to check and the location. Or do you think is something else. Please help. Thanks

 

I located the fuse that controls the locks. The fuse was bad, replaced and I'm OK
