My van has dual air controls for the cabin worked from a verticle slider with the two controls. Drivers side works normally but it blows hot air from the passenger side, even when the slider is set to the lowest (cold) position. The air conditioner operates normally, blows cold air onto drivers side only, although I assume it is mixing with the hot air coming into the cabin on the passenger side. What is causing this? I am suspicious of the temp control slider.

My heater in the Mercedes c240 1999 car is not working well. One side of the heater (left hand side is ok) but the right hand side keeps on blowing out hot air even when it is on the cold setting.
