I tried searching but never found any answers to this problem: my air flow is stuck blowing at my windshield and feet and I cant changed it to flow any other way. All the lights work when switching between the buttons and my heat/air works fine too. The fan speed works fine I can turn it up and down and it blows harder/softer. but never diverts the air to anywhere else besides the windshield/feet option. All my fuses are good as well. I read that there is a servo motor(s) that control the diversion of air between the vents but im not sure if that is what is broke or not. I hate to tear apart my dash to get to the servo motor when it could be an easier fix. Anyone that is familiar with a problem like this please help!!

 

I would love to know the answer to this. I've had the same problem for like 5 years. lol. stuck on the same position too.

 

I would say it's most likely your servo, u could swap in another heater control to try if u have access to one.
