Ive only used the third row a few times. Mine blows cold air in the third row seats (but I also have rear climate control)

The problem w/ BMW rear ac is that its not a second compressor, so when the rear ac is activated the front ac capacity drops 50%. When my rear ac is on, I cant cool the front cabin.

If you live in a hot climate like me, BMW AC simply sucks. It makes summer travel with the family a sweaty affair.
