Hey everyone,
I got in my Optima lx today and set the heat (cause it’s already cold in Wisconsin) to the defrost setting but most of the air came out of the floor vents instead. Setting the air to defrost and floor doesn’t change the air coming out, but setting it the vents does work. Does this sound like a bad blend door? I thought maybe the buttons could be bad that select where the air should be coming from.

Well, I found the problem, maybe this post will help someone down the road. The problem was the hvac mode control actuator. Since I removed it (after a lot of curse words), I figured I might as well dissect it to see if I could find the problem. I took the actuator apart and found a broken tooth off one of the plastic gears that was binding everything up. I removed the broken tooth and it was functioning again.
