The 40 amp fuse is for the fans.
Door locks have a 15 amp fuse
you have some sort of wierdness going on with control systems. Diaged it here is impossible without seeing and touching it. You need a good electrical shop that can track down these types of problems.
One problem area is under the battery. The harness melts from battery acid fumes and cuses opens and shorts. Thats the only lead I can give you at this time.
