Is there any update or ideas on this issue since? I have a similar problem. The vents were working fine. The temperature changes from A/C to heat and back, the issue is when I push a vent selection button it doesn't switch. Most air comes from face facing vents only.
At one point repair shop, "re-flashed" the PCM or something and it worked for a a couple of weeks. I replaced the PCM and am certain the thing worked, but stopped again.
Any ideas on this? Doesn't seem like it is the actuator motor to me but who knows. How impossible is it to check? Thanks!
