2007 GMC Yukon possessed

[dhow70]

Flickering headlamps, dash, interior lights, door locks lock and unlock, cruise and fog lamps turn off, traction control light comes on and off, hesitation for second when first crank of engine then starts, key entry quit working today.. I've replaced battery, post, headlamp switch, alternator checked, ground cables checked for corrosion, and even prayed and nothing.... My mechanic is at a loss, and the GM dealership I went to was a joke.... Any suggestion please?

There is a long drawn out procedure for what you're seeing. My 2007 Yukon xl did the same thing.. In my case it was a battery. Beyond that it had to do with the high speed LAN in the vehicle. I'll try to find it
