Locks and windows
Fuses need replacement? All the windows and locks? Start with the fuses. Even if they look fine, remove them, clean the contacts and replace them with new ones. If that doesn't work, for a little bit of pocket change, you have spare fuses. If it is only one door, check electrical connections going to the door. Do you have electrical connection or juice to the fuse box? Lose or burned wire leading to it. Some wires are bundled and held by a clamp. Wires do move and friction can remove the covering ans short out the wire causing it to burn and be an op;en wire. You've had the truck seven years and depending on the driving conditions and weather, it may be an open wire. Happy hunting. Finding electrical shorts are a lot better than soothing a wife or girl friend that you missed the birthday/anniversary date.
