2012 grand caravan rear heat issue

[mustang305]

Hello,

I took a longer trip with our van this weekend and noticed that the rear heat blows at max temperature regardless of the temperature setting. The van has rear heat controls and I tried adjusting the temperature at both the dash board and rear controls with no change in temperature.

Any ideas where to start looking?

Thanks

It's getting warm out and I'd like to get the AC working in the back of the van. Has anyone seen anything like this? 651 views on the thread now makes me a little nervous that I'll be letting the dealership take advantage of me to repair..

edit: I found my original log in information. yay!

Sounds like a bad mode door actuator in the rear HVAC.
