Power seats run off a 25amp circuit breaker in the dash fuse block. As far as power mirrors and locks, there are variations of wiring depending on the options you have. There is a 3 amp mirror/lock fuse. First I would pull back the door harness cover there between the door and body and look for a broken orange wire.
