Center vent not blowing at all?!
 

I just bought this Touareg 2004 V6. The center two vents don't blow. If I hold my hand on the vent i can sense the cold air when A/C is on a little bit but it doesn't blow. The ones on the side blow perfectly fine. I read that turning the heat on for 30 sec and than turn it back to cold can fix this problem and it didn't. Instead i found out that when i turn the heat on the passenger side is still blowing cold but the driver side blows hot. Any ideas please?
