Can anyone help with electrical issues? on 2007 GMC Sierra 1500

I have a 2007 GMC Sierra Z71 4x4. When I start it up, warnings come up and say that Hood is open, service tire monitoring system, service 4 wheel drive. Also, I have no power windows, locks, turn signals, no high beams and brake lights stay on. The wipers also do not work properly. Taking to dealer tomorrow. But any idea what it might be?

Will hopefully know tomorrow once hooked up to computer for the codes. Body Control Module? Hope is all that it is. Been having this problem off and on the past month, but always corrected itself until now! And always heard clicking noises under the dash!
