I have been working on changing out my heater core for the first time and i came across a little problem. I finally got to the big black a/c housing box and pulled it out. As soon as i pulled the halves apart a couple a/c door panels fell out. After exchanging heater cores, i put all of the panels back where they came from.. all except ONE. Can anyone please tell me where the heck this piece goes back to?


Where does this one belong? One side




Other side




One half of the housing box




2nd half of the housing box (side i believe that piece fell from but i could be wrong)
