I have a 2006 X5 4.4I and when I move the heat controll valve in the front to the red the air does not get warm. The rear gets warm no problem. Anybody got any ideas?

Well I had the cable on the vent controll checked out and everything is connected. I replaced the heater controll valve to no avail. I did find out that if I put the vent settings on the upper and floor area I get warm air when the vehicle is sitting still and at low speeds. When I get going up past 45-55 mph I get cool air through the vents. My temp guage is reading normal and the coolant temp is 187 degrees F. When I slow down or stop at a traffic signal the air gets warm again. Don't know what to make of it. may have to take to a mechanic.
