I'm having an electrical problem with my 1987 BMW 325 and not sure why. The instrument panel (fuel/tachometer/fuel consumption/coolant temp guages) are not working. Additionally, the heater fan and outside mirror adjuster are not working either. Everything quit, apparently, at the same time.
I've replaced the fuses but the problem persists. Not sure where or how to proceed. Any suggestions or recommendations would be greatly appreciated.
