Hi everyone! So my 07 H3 blows nice hot and cold air no problem, but not at the right spots. If I have it on face and footwell, it's fine. If I put it on defrost and footwell, it's fine. Once I put it on just footwell or half way between face/footwell, it starts coming out defrost. Kind of sucks when I get in my truck with cold feet and only have half the air pressure on them lol.

Now, one of my center vents is missing a blade for vertical control, and the other vent is missing a horizontal control blade so I'm thinking the H. Control blade may be stuck by a blend door?

Not sure if it's just a GM thing but I'm almost positive my parent's leased 2016 Sierra does the same thing, but I'm not 100% on it. I'll have to test that tomorrow to see if I remember correctly.

Thanks guys!
