AC/heat problem

When I turn AC on ,I get hot air on the drivers side and cold on passenger. I replaced the blend door at feet of the passenger side but didn't fix the problem. when heat is selected it works on both sides..?
This is on a 2016 F150 Lariat dual temp

Your driver's side actuator is stuck on "hot".

You replaced the passenger side actuator, not the driver's side one. It's on top of the plenum.

Hmmm , this is the one I changed but still getting hot on the drivers side when AC is on. Maybe the damn door itself is broke....

Got it working. It was just a matter of getting the cam lined up in the correct position. That is the blend door for the drivers side with dual climate controls.
