2013 JKU heater-AC temp control

Hey guys - replaced my heater core using s short cut method - actually required three cuts / whole different story for later.
NOW the temp control only works on extreme cool and hot. I know the blend door functions - any clues for testing the actual rheostat control would be always appreciated.

I think the dealer might be able to re-calibrate it if you haven't already had it in for the heater core issue. I just replaced the whole HVAC control as mine was out of control with temp and blend door positions.

4 1/2 hours - not bad considering my first JKU underdash exploration. Really Quite simple to figure out. Just have patience and think it through. Watch plenty of YouTube videos.
I plan on posting the 23 pictures I took in doing it - I just haven’t figured out how to post them (yet)
