Asked by for the 1991 Mercedes-Benz 420SEL
that is some bad information jump it or charging the battery wont hurt anything
thanks for the help im taking it out now to replace it--charged it up car runs-- now i dont have power windows and my light sw dont work,and my ABS light stays on any ideas fuses look good
its going to take some time for the ecm to learn all computer controlled equipment
well two main things windows and lights--the light switch wont even turn--start to think some moisture got to it or something --going to try and pull it today if the rain stops--been two days car runs fine but the two things have not changed--dont even know where to start with the windows
