Yeah, I keep the fresh air vent closed until spring. I did a little digging around during lunch and found a couple problems. There is a cable that controls a door for the lower two vents on top of the transmission tunnel. It opens the vents when in "heat" half open in "high-low" and closed in "defrost". When I move the switch in my car, it adjusts the other doors in the box properly, but is not actuating the cable for the lower door. So I manually opened the door with the car on and fan running to see if it was working and was greeted by a blast of old leaves, carpet padding, twigs, and somehow, a figurine of a small monkey. I then had to dig about another handful of debris out from the door area with a coat hanger to get in the tight area. After I did that, heat seemed to work good from the lower vents, just have to fix my control head for automatic operation, lol.
