Question about Cars & Trucks
AC/Heat controls work fine for driver and passenger side. I turn on rear blowers with AC on and the air is warm (not cold). I had read that the rear blend control could be behind the rear passenger side quarter panel. I want to know where it is located and how to get to it so I can replace it. Please provide detail instructions if possible.
Hi Jim, I'm glad to help!
Jim, first you'll need to get the seats out of the way. Next remove the rear quarter panel. The blend door motor will be right in front of you mounted on the side of the Rear A/C Housing. It's been known to go bad. BUT, sometimes the door itself breaks, so you'll need to check that. But most importantly you'll need to make sure it's getting power and ground from the control unit because I have found is some cases it's not receiving power and ground to the motor. You can check the motor by applying power and ground from the battery to see if the motor is good. Hope this helps and have an awesome day Jim.

there are separate actuators for the blend doors. one for heat and one for cool. they work opposite and in conjuction with each other, if that makes any sense. ones open, ones close, for each different climate. sounds like the the cold one isn't opening in the rear.

Actuator motors either get a tear in the rubber or a hose is broken and not letting vacuum assist in its opening.
You can try moving the lever by hand and see if the air gets colder on the bad side.

Air Temperature Control Blend
Door Failure No Heat
In all modern cars there is a tiny DC electric motor driven gear drive that moves a plastic door that blends heated and cooled air from the AC and the heater core, this is called (interestedly enough) the air temperature control blend door actuator. The motor that moves this door fails because the door starts sticking from warping, most common complaint is no heat but it can be no AC as well. To replace these parts (blend door and blend door actuator) you must remove the entire dash from the car. Always have this problem confirmed by a dealer or qualified repair shop as it is a very expensive repair.
