Can anyone tell me if the W210 dual zone heater has a temperature sensor in the system, or does it just pump out constant temperature air? There appears to be a hole for a sensor of some kind in the overhead panel.
If there is a sensor, could it be causing the heater to output hot air on the passenger side occasionally when the control is set to the white position. I can make it go back to normal by moving the drivers side control to hot,and then back to normal. Moving the passenger side control has no effect bizarrely.
