What is your question?
The rear blows very cold. But the front blows hot regardless of the control setting. It also barely blows out of the vents in front. Does anyone have any answers? I have been reading and seeing a lot of info on fixing the vacuum controlled actuator in the glovebox as well as the the blend door behind the dash. Does anyone have a suggestion. This is my son's first car.

The air flow mode doors that direct where the air comes out of are vacuum operated. A vacuum leak or detached hose could cause a concern here, but that's only one possible cause of failure. The temperature control is driven by blend door motors (2 if you have driver and passenger separate dual zone climate control system, 1 if you have the same temperature across the front). This motor can be faulty, but I've also seen the plastic plenum behind the dash that holds the temperature blend doors be physically fractured. So this could get quite complicated. Listen for a "clicking" noise behind the dash when turning the temperature control knob to the position you are hoping to get to. You could also have some kind of other concern with the front air conditioning, but since the rear is cold, I do not think it's a question of the system functioning under the hood properly. Good luck!
