Electrical Issues! Uconnect screen not working when truck is running!

[Ramdeathstar]

So, when I turn on the accessories by just pressing the ignition button without the brake, I have no issues. The display screen works, radio functions, climate control works, and front window buttons work. However, once I start the truck completely, the screen shuts off, all climate control functions stop and I lose only the front window buttons (rears work fine). Super frustrating issue and really can't wrap my head around it since it works just fine under accessory power. I was thinking maybe a loose connection somewhere? Maybe a fuse? but still why would it be so consistent under accessory power then just immediately shut off once the vehicle is started. Any insight and advice would be greatly appreciated!

Update! So I kept getting the message that my right rear turn signal was out, however it always still worked as I would see it illuminate in my side mirrors. After taking my car to the dealership where they ran diagnostics on it, they determined that a short caused by that same taillight is what caused all my other electronics to stop working properly. So just wanted to update this post incase anyone runs into this same issue.
