My mother's 2008 Honda Odyssey LX is stuck blowing out the front vents, the hot and cold mixture is working fine so I don't think it's the blend door actuator, I found some videos online where there's a mode selection motor above the blend door actuator but that doesn't appear to be how it's setup on this generation of odyssey with mostly base model options, because I took off the driver foot air duct and I can only see the blend door bit which seems to respond as normal when you adjust the temp dial, what is responsible for changing which direction the air blows?
