2015 Tahoe LTZ/Replaced blend door actuators/Now will not crank or start/Help!

[Capt America]

Hey guys Capt America needs your help. I replaced both blend door actuators so both sides get cold air. I had to unplug and remove two electronic computer modules behind the glove box to gain access to top actuator. Now, the Tahoe will not start/crank. Tried resetting by disconnecting battery and still nothing. Tried draining all power by connecting terminals for 15 minutes and still nothing. WTH. Anybody have a solution? Thank you.
