View Full Version : Heat & Cold at the same time! whale 06-18-2009, 01:48 PM The A/C dash vents in my friends 850 output heat on the drivers side and cold on the passenger side when both driver and passenger buttons/rotors are calling for cold? While this is happening both driver and passenger door vents are providing cold. Why would the drivers door outlet be flowing cold when his center vent is blowing hot? What would be his problem source? whale 06-21-2009, 08:29 PM bump!
