I wish I had figured it out before tearing the dash all apart checking the recirculation door.

I could never do that or watch it being done. Just to painful looking for me. As a side note, had it charged and dyed 2 years ago. Still blowing cold air but now the fan on high is louder :) Forgot to check to fan on high with the heater going.
