I can turn my fan on HIGH with the slide on cool/cold and there is tons of air that blows out of the vents. When I move the bar over to heat/hot the volume of air is cut in half. I can hear the fan roar but very little air is coming out. For the few of you that have changed the heater core, was there alot of trash behind the heater core? I can't figure out what's choking off the air flow.
any ideas??
thanks
