HVAC Control Buttons Do Nothing After HMI Install

Hey everyone! I just added the infotainment CarPlay upgrade to my 2014 stingray.

I followed the instructions from their site and everything worked great!

However, now my HVAC buttons don’t work. The lights are on, but they don’t change anything. Air only comes out of the dash vents, not the feet or the defrost vents.

Any idea what could have gone wrong?

I’m assuming I missed a wire or something, but I’m not really sure where to look here. Any help would be greatly appreciated!
