The LH front power window control switch receives power from the delayed accessory relay through circuit CBP47 (GN/BU) and is grounded through circuit GD133 (BK). When the LH front window control switch is pressed to the UP position, the LH front motor receives power through circuit CPW11 (BU/GY). When the LH front window control switch is pressed to the DOWN position, the LH front motor receives power through circuit CPW10 (YE/VT). When the LF window motor receives a ground signal on circuit CPW29 (VT/GY), the LF window motor will enter one-touch down.
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Inoperative LH front window motor
- Inoperative LH front window control switch
- LH front motor not initialized
