2003 2500HD Crew Cab, D/A, very base model.

This morning when I got to work, the right (passenger) front door had no power, no power lock, no power window, from either the driver or passenger control. It was OK when I left the house, because I rolled up the window. The accessory delay doesn't work either, the radio and windows shut down immediately when the key goes off. Also neither remote key fob will work.

A quick check of fuses (without pulling them) doesn't show any obviously blown. Can all these problems be related to one circuit?

Thanks,

Bob
