Electrical Problems

Hi, my name is Jay.. I have a 2002 BMW 330 Ci. Recently the cars been acting up with electric problems.. Engine light is on, but what I'm trying to troubleshoot are issues like turn signal light goes off on it's own, but no blinker light is showing from the outside..Another is Radio switch on the steering wheel will not work.. Just the car has a mind of it's own..Liked to get an idea of what's wrong before I possibly have to take it to the shop if I can't fix the problem myself... Thnks Wayne..

Electrical problems can be difficult to troubleshoot. I'm not sure what you mean by the blinker going on and off, and the light bulb outside not working. Some of those issues can be caused by poor grounding, or some corrosion in the light bulb sockets - I would investigate the bulb socket and see what it looks like. Some sandpaper applied to the contacts within the housing can sometimes do wonders. The radio switch may be a problem with the switch itself, or with the radio. Then again, all of your problems here could be related to a steering wheel wire harness problem. It's anyone's guess at this point.
