Possible fix for blend/mode door problem

[03greenZ71]

This may or may not help anyone but my favorite YouTube mechanic, Eric at South Main Auto, just posted a video diagnosing a blend/mode door problem where it won’t switch from defrost back to floor or vents. He found it to be the vent door foam being worn out and gone letting the motor overextend and stop working. I hadn’t thought of this ever being the problem, so maybe it will help someone else too. Link is below.

Yeah I wish I had an honest mechanic like him close to me.

I just installed that exact actuator last weekend. I would love to see how he gets it into position and if he takes the seat out which I did. It took me several tries and lots of frustration to figure out the install process. Anybody can remove it installing it and getting it to work properly is not as easy.
