06 Montego only blows air out of defrost vents....wondering if there are check valves, or blend door common issues I can go check?

I had that happen once; we used to have an '89 Plymouth Sundance, and when the actuator for the blend air door went out, it got stuck in the defrost position. Never did fix it; the radiator started leaking, it repeatedly ran out of coolant, and the engine block cracked. A replacement engine - in this case, used - was more than the car was worth at that point, so since we had another vehicle, we simply got rid of that POS.
Where did you have the HVAC set to before it started doing this? If it was on the defrost setting, it may be that the blend air door may simply be stuck. Have someone take a look and see if they can unjam it; if you disconnect the actuator, and the door can be moved by hand, the actuator needs repaced.
