C1-C2:

C2-C3:

C3-C4:

NOTE:
- A new LH front power window motor will only operate in proportional UP or DOWN mode until initialized. Refer to Door Window Motor Initialization. Testing and Inspection
- The LH front power window motor must be initialized whenever a new motor is installed.
- The LH front power window motor must be de-initialized, then initialized whenever the LH front window motor is removed from the window regulator drum housing, a new window regulator is installed, a new window glass is installed, a new top run is installed or for any operation in which grease or lubricants are applied to the window regulator or glass run.

Normal Operation
Under normal operation, the LH front power window control switch receives power from the delay accessory relay through circuit CBP02 (GN). The LH window motor receives battery power through circuit SBB34 (YE/RD) at all times and ground through circuit GD126 (BK/WH). When the LH front window control switch is operated in the UP position, the LH front window motor receives a voltage signal through circuit CPW11 (BU/GY). When the LH front window control switch is operated in the DOWN position, the LH front window motor receives a voltage signal through circuit CPW10 (YE/VT). When the LH front window motor receives a ground signal on circuit CPW29 (VT/GY), the LH front window motor will enter one-touch up/down mode.

Possible Causes
- Fuse
- Open in circuit SBB34 (YE/RD), CBP02 (GN), GD126 (BK/WH), CPW11 (BU/GY), CPW10 (YE/VT) or CPW29 (VT/GY)
- Inoperative LH front window motor
- Inoperative LH front window control switch
- LH front window motor not initialized
