So..... How's it suppose to work??? You hit the button and the blower comes on in the rear, you can adjust the blower speed, but can't adjust heat? Is it just A/C? Doesn't look like a heater core is installed... Anyone know how factory rear A/C is designed to work?

 

It's a separate system with no heater core. If working, it will recycle rear air while cooling it.

 

hmmm. Thats why im freezing my naanaa's off. Makes sense Guess it will be great in the summer, especially with all those windows...
