Hello all, Ive noticed some weird symptoms here. Im hearing some sort of buzzing on the drivers side of my 560sec, mostly when engine is cold, and most consistently does it when braking and going over bumps. It sounds like a small motor buzzing either behind the dash or footwell. Ive also noticed that when Im driving say on the highway, some air does come through the side and top vents even when the AC/heater is off. Its annoying cause its usually cold air which is forcin me to constantly run my heater. Feels like air from outside coming in. Are these two annoyances related? Am I leaking vacuum? I read a post about the HVAC.... but dont have any experience messin with climate control stuff. Any help would be appreciated. I love my cars!
