Check your mode door actuator, behind driver's side knee bolster on left side of HVAC housing-- you must lay on your back and use a flashilght to see it.

See if it is moving, not binding, if all armas are connected, not flopping around.

Lat on I did had a plastic Walmart bag sucked up into recirc door- but his complaint was blows good until you hit recirc button.

very common problem you bend door is control by vacuum and when it looses vacuume it defalts to defrost. Under the hood on the passager side there will be a small plasic vac line coming throw fire wall going to the top of the engine manifold, follow that vac line and check for leaks if it is leaking repair them and that will fix your problem
