Sudden electrical component failures

All of a sudden the following electrical components stopped working at once: radio, power door locks, and power trunk release. Fuses appear fine.
There's a couple of relays for the power locks which I have not tested. Any ideas where to start checking?

Did you check fuse M1 ( 10 A) in underdash fuse box?

I don't see anything marked M1 inside the fuse panel on the left side of the dash. The cheat-sheet on the back side of the panel says, #1 is a 5A and is marked as Power Mirrors, #2 is a 10A and is marked as Radio. Both test OK with DMM. There's a large 20A metal fuse marked on the cheat-sheet as Power Seats and Locks. It also test OK.
