Quick question. 2010 LX my blend door is not secured to the actuator tip. I see the tip moves when I change from recirc to fresh air. The tip is loose and not in the hole in the blend door. I read all about having to put in record mode before changing the filter. My main question is the hole in the blend door a complete circle or does it have a little gap at the bottom? Mine doesn't look like the other photos of cracked and broken pieces in that circular area so I am hoping that gap is supposed to be there and I just need to re seat the door onto the actuator tip. Any idea?
