Why does the rear AC blow warm air?

Try turning the temperature control of rear system and see if it blows hot air when you turn it to full hot position. If that works, please reply back and there is a quick diagnosis that you can do to figure out the problem.
How does the hot air blow in a GMC Yukon?
A small servo motor that turns hot and cold air valve in the heater box. I pulled the small flat motor off and noticed the shaft was jammed and would not turn when i moved the temperature selector knob from hot to cold.
What’s the difference between the front and rear AC?
It was about 80 degrees outside and my ac temperature settings were at 65. You could really feel the difference between the front and rear. Try turning on the rear controls but did not help either. Anyone else experiences this issue. :help:
Why does my car blower make a strained sound?
If I turn the rear control behind my head to hot, the blower sounds really strained, and nothing comes out the back. I am assuming there is a door that has to open, near the passenger door, because that is where the strained sound comes from. It sounds as if the door is stuck, and will not open the other way.

Why is the front vents warm but the rear vents are cold?

Why does my front AC blow hot air?
Warm in front, cool in back. Please post any answers as I would like to know as well. a/c is working fine. sounds like the diverter door is remaining open allowing the fan to blow air through the heater core. this door is often controlled by engine vac or and electric door motor closing device. A good mech at the dealer should have found this.
Why is the rear AC warmer than the front?
When the rear ac is turned on only, the air isn’t that cold. But when the front ac is turned on, the rear ac is blowing colder air out the vents. That’s because the rear AC by itself can’t turn the compressor on… The front AC has to be on for the compressor to turn on….

How does the rear AC work on a GMC Acadia?
Also, if you don’t have anyone sitting in the back rows, use the mimic functionality for the Aux unit. i.e. set the front unit to whatever you feel comfortable with and then cycle the Aux button off and on. This will bring the rear also in the same settings as front and will be pretty comfortable.
