My 750I with 50k miles the air conditioner blow cold on the passenger side, hot on the driver side after rising the temperature to a warmer temp like 72 . I can’t get it to cool back down. I have both sides set to the same temperature. The car already been at the dealer for that issue twice, first time I was told it was normal could not duplicated the problem. The 2nd time they said I was low on Freon still no problem solve. Any Ideas what could that be.
