The left fog light (stock) on my 87 325 was flickering on and off for a while when I went over bumps and such, as if it was a loose connection. Now it is off all the time. I have wiggled the wires around the light itslef, but it does not make the connection. Where should I look for the break in the circuit? People always talk about the wire cluster or something, but I don't really understand what that is. Specific advice is GREATLY appreciated, as I am not exactly an electrician.
