Door locks acting funny

[1-3-2-4]

Ok this is starting to happen.. walk up to car and unlock the drivers side and no other doors unlock.. so I lock my driver door and driving down the highway the doors all lock..

So thinking it was the drivers door I checked it out and nothing... UNTIL this afternoon I happen to have my door locked and closed my glove box and the doors locked! So I unlock my door and the rest never unlocked until I closed the glove box again.

Now that had me thinking how in the heck can the glove box influence how the rest of the doors unlock?

just a guess, but must be an electrical short. loose connection.
the glovebox may be wiggling a wire just enough to engage the connection.

also, while driving down the highway, you could have shook it just enough.

Check your relays for the door locks.

Is it near the fuse panel? I noticed while driving tonight with the doors locked the doors ever so often keeps trying to lock it's self when it's already locked.
