Hey!! we need help. 2015 suburban LTZ. AC front blowing lukewarm air but not hot, back ac working perfectly. we have filled freon and it is showing 46psi. took out filter in glove box (it was nasty). so we think it may be the blender doors but doesn't it have one on each side? don't think its likely for both to go out at same time. Advice??? what should our next step be?

Dealing with A/Cs, I'm already very confident that your A/C system is fine since the rear is operational. I think you have the right mindset to think about the blend door.i would do the first check in this video to see if your blend door is OK and to see if your actuator is not operating properly
They even go so far as to tear everything apart to show you how the internal components are operating
