Not great.....may have a random rogue vacuum leak that i can't find making my A/C go thru the defrost instead of vent

could be the baffle itself.. sometimes the actuators go bad and fail to work... course have noticed in my truck it gets confused at times too... usually playing with the switch solves it...
