A/C Vacuum
oh and just one more thing....why does hot air only come out of the side vents when the heater is on? wondering if this is just a programming issue and if i could fix it....thanks again
thanks in advance....and have a happy new year
Mercedes engineering says that hot air shouldn't come out of the center vents, for reasons unknown to me. During the wintertime, I get about a car per week with the complaint "Check no hot air from center dash vents." That's how they all are, they can't be programmed otherwise.
