mercedes 97 E320
 

my front left side marker light some time work, other don't work, if anyone have fix this problem, is a sensor for control this function ?, if is a sensor, where is located ? for Mercedes 97 E320

Replace the bulb and see what happens. While you're in there take a close look at the contacts.

I check the contact, bulb is ok, power in this side is failing and when to I turn the light on the power switch in the panel failing bulb is coming on, I think That Have to be with some light distribution Control module, i dont know where is it

give this a try - wiring diagram

Thanks you, that helped a lot, now I have to find where is this "Iluminetion control module"
