My car is a 560 1988 sl. I hope I can get somebody to help me with this. The issue is that as soon as I step on the brake pedal , the burned out bulb warning ligth onthe console, ligths on and stays on all the time. On checking the ligths , the third brake ligth (mounted on thr trunk lid) does not ligth up. I changed the bulb, but it still does not ligth. I checked the fuses, but they all seem ok. Obviously there is no juice to the ligth, but i do not know where to look now, or how to check the wiring. Can anybody help? I tried to search this web site, but no luck. Any ideas will be much appreciated.
