Hi fellas, here's another question that I know has been answered before, because I've seen the answer but I can't find it again.
The interior lights come on when I open any door except the driver's door.
So, the question is, where is the switch that turns the interior light on?
Thanks.

 

It's integrated in to the door latch assembly.

Search on ebay for X300 Door Latch and you will see pictures.
