Cha-Ching!!!!!!
Watch them charge you $5,000 to replace every last part of the the AC system, when I'm 101% sure its just a wire you forgot to connect back up!
Man I wish I was your BMW Dealer. Them nuggas pray every day for people like you to come in with that sort of thing.
Just re-check all your wiring connections. Dude, it's normal to forget to hook something back. We are human...after all.
