I have an 07 escalade and am not sure if the air is flowing through the roof vents in the rear how can I check to see if there working.

Turn it on and place your hand over the vent.

Thanks for the advise. My understanding of how the controls worked is that you can control the air flow for the rear vents from the front but i guess you can only maintain the temp the same as the front and control the flow of air from the rear controls. Is this correct. The air flows from the vents when I control it from the rear.

I have a 2010 and there is a button up .front that sets the rear to the same setting as the front

When you set the front to auto the rear is set at the same temperature. Can you manually adjust the front controls to set the fan on for the rear overhead and floor vents.

Yes sir. I believe the back only mirrors the temp of the front, regardless of where the air up front is coming out.

Im not actually at home right or I would verify what Im saying.

Just manually ramp up fan setting to high speed and set rear to auto...I just verified mine blows to rear roof ducts big time..

The controls for the rear climate are on the back of the center console. Turn the system on and then sit in the rear and you'll see the controls active. The buttons for the rear seat heaters are located there as well.
