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!!!!
