I am also having the same codes (52,56) I have no passinger side heat and I can hear at times the recirc door hit the blower fins. I am in Florida so I intend to fix the blend doors and also the recirc door. The fix at JustforJeeps seems easy enough to do but I am confused about the recirc door. I don't know which direction is which. I would like to close off the outside air and screw or zip tie it in place. I am unsure on how to fish it out of the blower. Do I have to remove the blower then push it into place? Do I want the door in the closed position? Any pix? From the Pix at the start of this discussion, it looks llike the only way to get to this door is with blower removal. Blend Dor does not say how to do this fix and they do not post instructions. For $5.00 I guess the kit consist of a couple of zip ties and instructions.......but then I don't know for sure.
