I believe this climate control system is not specific to the 2009 R350 that I own, so I wanted to put it out there for the General Tech folks. My climate control system is pictured below. There are two knobs left and right which are the driver and passenger temperature controls. Each knob has a red indicator light (when the system is turned on) that illuminates above the temperature selected. I can select any temperature and the indicator light moves, BUT the indicator light on the right (passenger) blinks or flashes constantly and the temperature changes are sporadic. Does anyone know what causes the light to flash while the light on the other control remains solid?
