2009 Mazda 5 4 cyl Front Wheel Drive Automatic
Where are the blend controls for the rear hvac? The blower works properly but will only blow cold air out of the rear vents. The front works fine. I suspect it is the blend control for the rear, I just don't want to start ripping the whole interior apart to find where they are.
There are none! The heat comes from under the front seats only when heat is on. Take a look and you will see vents under the seats. The rear hvac ONLY blows cold air. It's in small print in the manual. Sorry, I found this out the hard way myself.
