    Interior lights dont work after replacing heater core

    So I just finished replacing the heater core in my 98 blazer and the instrument cluster doesn't work, interior lighting doesn't work and the door locks don't work. Did I leave something unplugged or did I miss a ground somewhere? I'm at a loss and need some help.

    Sounds like you may have left one of the harnesses unplugged behind the dash.
