CHECK THE GRN WIRE, THE MERCEDES SHOP BANG ON THE LIGHT MY FOG LIGHT WAS WORKING AT TIMES AT THE MERCEDES SHOP, I REMOVE THE TWO BOTTOM PANELS AND FOUND THE PLUG CONTACT USE CONTACT CLEANER, THE LEFT H7 HEAD LIGHT WAS OUT REPLACE AND A WEEK LATER THE RIGHT HEAD LIGHT OUT, REPLACE

Thank you RAYMOND.

BTW...Notice you use CAP's a lot...any reason why ? Anyway...I will trace the wiring back to the SAM later and report back.

...My 'Mercedes' Snap-On is only through 2000 yr. Am updating it soon, although am looking at the LaunchX for better interrogation of Mercedes.
World Pac does them I believe.
