Hi, I have a 2010 W251 R Class. Sometimes when I open the driver side door, the interior lights don't work. Sometimes, it works. There is no door senor button like older Mercs. ONLY the driver's side door has this problem don't see any sensor like devices around the door and sill. Any ideas on repair or direction on what I should check is appreciated! Thanks in advance.
