Electrical Problems

2003 Super Duty V-10
Most automatic functions have disappeared. Automatic headlights, Automatic door locks, Key warning sound and courtesy lights. Also the radio doesn't turn off when opening the door with the key removed, but still times out after several minutes. Are these automatic functions controlled by the GEM or some other module. All fuses and relays are working OK. The head lights and electric door locks work fine with the manual switch. The gong warning sound works for seat belt warning only. The front door interior light switches test out OK.
