Help with ACC on my 2009 M3

Hi All,
I recently removed the dash to update stereo with Apple CarPlay module.
After reassembling, my vents were not blowing at all. You would hear the noise of fan, but nothing coming out. The only air was coming through the vents in backseat. Perhaps unrelated, the only air out of back seat vents was hot - even though AC was on.
Is this a fuse? Dirty air vents? Etc?

Thanks!!!!

Check the connectors on the back of the AC controller ... ensure they're seeded properly. I had a similar issue caused by the right (white I believe) connector not seeded all the way.

I don't mean to stray off the topic, but what kind of head unit did you install? I was going to update mine as well and was looking for ideas.

Any help would be appreciated, thanks!
