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
The LH front power window control switch receives power from the delayed accessory relay through circuit 1499 (PK/LG) and is grounded through circuit 1205 (BK). When the LH front window control switch is pressed to the UP position, the LH front motor receives power through circuit 226 (WH/BK). When the LH front window control switch is pressed to the DOWN position, the LH front motor receives power through circuit 227 (YE). When the LF window motor receives a ground signal on circuit 2018 (OG/YE) the LF window motor will enter one-touch down.
Possible Causes
- B(+) power lost during LH front window operation
- Inoperative LH front window motor
- Inoperative LH front window control switch
- LH front motor not initialized
- Open in circuit 2018 (OG/YE)
