Ventilation problem on the rear bench
 

I have a BMW x5-e70 3.0d 9 / 2007 and I have the same problem as well as in the previous BMW 5-e60 3.0d 12/2003. Winter on the back bench constantly blowing cold air even though it is tem. on the display 28 degrees, which of course creates a problem for travelers on the back. Does anyone know what the problem is? Dealers do not know!:banghead:

Bothers me that I would most changed the car!!!!!!!!!!!
