    no power to windows, blower motor fan, or sun roof

    I just swapped out wiring harnesses for my m52 in my e30 after having issues with my first one. Just pulled it out of the garage today to find out I can't roll my windows down or my sun roof. Went to just blow air through my vents and no power there either. But my clock, radio and everything on my dash works fine. Tried to check the powers and grounds but couldn't find anything irregular. Any suggestions??

    Check your starter wiring. I had the top wire break at the connector

      That sounds like the unloader relays aren't engaging. Which would mean that the unloader control wire from the engine harness isn't connected the unloader switch in the starter solenoid or that the unloader switch is bad.
      The car makes it possible, but the driver makes it happen.
