I can not get any air flow from any vent which means no heat. It doesn't matter where the knob is turned to- defrost, blend, A/C no air comes out of any of the vents. That is bad when you live in northern Illinois. I haven't been able to get the problem fixed because until I ran across this no one was sure what the problem was.
