Refer to Wiring Diagram Set 100, Power Windows for schematic and connector information. Diagrams By Number

Normal Operation

Under normal operation, voltage is supplied to the LH front window control switch from the accessory delay relay through circuit CBP47 (GN/BU). Ground is supplied to the LH front window control switch through circuit GD134 (BK/VT). When the LH front window control switch is pressed, voltage is provided to the LH front window motor through circuit CPW10 (YE/VT) and ground through CPW11 (BU/GY) to operate the LH front window downward. When the LH front window control switch is pulled, voltage is provided to the LH front window motor through circuit CPW11 (BU/GY) and ground through CPW10 (YE/VT) to operate the LH front window upward. The one-touch down feature electronics are integral to the LH front window control switch.

This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- LH front window control switch
- LH front window motor
