A/C Questions
My 2000 C280 Sport has the electric climate control and when the ac or the heat is on I hear like a thumping sound comming from the center and right vents. Is this normal? or a serious problem. When it is on full blast heat or ac the thumping stops but when it is low I hear it. Also when you turn the car off should you turn off the ac or can you leave it on?
