Can't get my heater working!

It's starting to get pretty cold out side and I'm trying to get my heat working. Any ideas would be greatly appreciated! When I switch to heat my airflow is significantly reduced and the air comes out lukewarm at best. I replaced the blend door actuator because it was not moving all the way. When I opened the old one some of the gears were broken. I thought I had solved the problem but no... It still hardly blows and air and it isn't warm. The blower motor is working fine and doesn't slow down on heat. Could my heater core possibly be restricting air flow? Possibly my blend door is broken?

Check the cabin air filter in the door behind the glove box. There are two filters that sit side by side in there. If they have never been changed they could be severely restricting airflow. They do get pretty gross after a while, and should be replaced every 12k miles (or sooner if you drive dirt roads a lot).
