2000 S430 Electrical Problem

[HMB]

HELP!!!! I need help to find a solution to this problem. I think a controller or something else has gone bad.
No electric windows, no locks, no seat control, no rear headrest, no rear blind, no A/C controller, ABS light is on, cluster is giving all kinds of warnings, airmatic pump is on all time.
I have checked all the fuses in the three fuse boxes. Could it be ignition switch? HELP
