I have this same problem. The climate control system went out. It wont control the vacume system to open and close the vents. You either have to replace ($600 delership or $200 yourself and very easy todo) or pull out the vacume hose contector to it and buy $1 hose to conect the blue hose to the yellow one. this turns on the front vents.

There must be a blender door somewhere that is not opening or closing it could also be the control system itself i suggest you let someone check this out a qualified shop.
