Default 96' Park Ave Heater display not functioning after intake replacement

Hey guys,
I recently did some work to my 1996 Buick Park Ave with 200k including replacing the Upper and lower intake gaskets, alt and battery, spark plugs, serp belt and tensioner and so on. Before I did this work the heater display did work (although the heat did not), and was wondering where to start to at least get the display working again so I could diagnose the heat problem. When I did the gaskets I had to disconnect most of the wiring harness so im assuming it has something to do with that? I checked all of the fuses under the drivers side and in the engine bay. Any help would be great,
Thanks!

I can post one when I find my camera but basically the display is completely blank and does not respond to any of the buttons/functions/etc. Is there any wiring that could have been disconnected for the display power when I disconnected most of the wiring harness? All the other electronic components still work great in the car so its strange why this single display will not work

Let me see if I saved the diagrams for that, before my AllData subscription expired I saved a lot of diagrams I thought I may need in the future.

Ahh, here we go.
