I had this problem just the other day! My heat was working, but I was getting the flap, for sure! Pull the three screws holding the blower motor in place (the last one in the corner is a dog to get to, you'll need swivel joints and whatnot), and inspect the squirrel cage. Mine had leaves in it, acting like cards in wheel spokes... Pull those out, and you should be good. I am assuming, you may have more in there, preventing flow. Good luck!
