July 1: So it begins. Don't worry, this is not in the correct legal jurisdiction!

Both Power Mirrors Do Not Operate

  1. Disconnect outside power mirror switch. Connect test light between Orange wire and ground. If test light illuminates, go to next step. If test light does not illuminate, repair open circuit in Orange wire.
  2. Connect test light between Orange and Black wires. If test light illuminates, repair open circuit in Red wire. If Red wire is okay, replace power mirror switch. If test light does not illuminate, repair open circuit in Black wire.
