When any of the up switches are operated, battery voltage is supplied to the window motor through the Dark Blue (164) wire. The window motor is grounded through the DN contact. The motor runs to drive the window up. When any of the DN switches are operated, battery voltage is supplied to the window motor in the opposite direction through the Brown (165) wire. The window motor is grounded through the up contact. The motor runs to drive the window down.
