The 3 position rear cargo light in my 99 ML seems not to work in the "door" setting. I looked all around the door jamb for a switch that indicated that the door was open or closed, and I didn't see any type of mechanical switch. Is there such a switch and if so, where is it? Is the problem likely to be in the door switch or in the light switch on the interior ceiling?
