When any of the UP switches in the Power Window Master Switch Assembly are operated battery voltage is applied to the window motor. The window motor is grounded through the DOWN contacts of the Power Window Master Switch Assembly. The motor runs to drive the window up. When any of the DOWN switches in the Power Window Master Switch Assembly are operated, battery voltage is applied to the window motor in the opposite direction. The window motor is grounded through the UP contacts in the Power Window Master Switch Assembly to G304. The motor runs to drive the window down.
