I need help with a probem on a 1992 300SE W140 , yes its the first year of the W140 and it has a few bugs but I love the car. It seems at any time the right directional light will come on and stay on even if the ignition is off, this is a problem since it drains the battery. When its on, both the front and rear lights are on and the arrow directional on the dash, it comes and goes with no reason, is there a light control module or maybe a flasher unit??? Took it to 2 shops couldnt find anything wrong, but I dont really think they checked it. Any help would be appreciated or if you could reccomend a shop in the nort NJ area.
