Hello, I am the new owner of a 2001 outback with the 3.0. I am having trouble with the heater not working properly. When you first drive the car a few miles & it warms up the heater works great on the auto setting, but, after you drive for 15--20 min. The heater basicly stops working. The blower fan still blows but you can not feel any air comeing out anywhere. The fan sounds like it tries to change from vent to floor & ect but it does not. If you are stopped long enough for the motor to realy cool off then the heater will work fine for 15 min or so. Has anyone else had this problem? Please help.
