I have a 1999 Frod Expedition and I have only had it for a few days but noticed that when I go to lock the truck 3 of the for doors will lock and one will not why is that. All the door will unlock but I have to manually lock the door when getting out. What can I do.

Hello hutchjer

Welcome to 2carpros.com

You did not mention which door do not unlock but that is ok
according to the diagram the driver unlock relay is separate from all lock and unlock relays.
replace this relay to take care of the problem.
