E320 A/C blows out defrost duct when accelerator depressed
Most of the time when accelerator is depressed the 2 middle vents will stop blowing & will start blowing through the defrost duct somtimes even seems to be blowing out somewhere else other than defrost duct being that I dont feel air coming out. When foot is lifted from accelerator the middle vents miracously starts to blow again. The 2 outside vents are not affected. Also, when system is on high it seems to kick into highest speed with a delay.Any advice would be much appreciated.
