Power locks

My power locks quit on my 93 grand prix today, both on the keyless and on the door panel. At the same time, my trunk release on the remote quit, not sure if these are related, but I would guess they are. I first looked for a fuse, but the book shows two fuse blocks with fuses for power locks, but I can only locate the one under the dash. Does anyone know where another fuse is located for power locks or have any other idea for fixing this problem? Thanks in advance for the help.
