PINPOINT TEST B: A SINGLE POWER WINDOW IS INOPERATIVE-LH FRONT

B1-B3:

B4-B5:

NOTE:
- A new LH front power window motor will only operate in proportional up or down mode until initialized. Refer to Window Motor Initialization.
- 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 1499 (PK/LG) and is grounded to chassis through circuit 1205 (BK). When the LH front window control switch is operated in the up position, the LH front window motor receives power through circuit 226 (WH/BK). When the LH front window control switch is operated in the down position, the LH front window motor receives power through circuit 227 (YE). When the LH front window motor receives a ground signal on circuit 2018 (OG/YE), the LH front window motor will enter one-touch up/down mode. The LH window motor receives battery power through circuit 995 (GY) at all times, and delayed accessory power through circuit 2086 (RD/LB) when the key is ON and the delayed accessory feature is active.

Possible Causes
- Inoperative LH front window motor
- Inoperative LH front window control switch
- LH front window motor not initialized
- Fuse- Open in circuits 226 (WH/BK), 227 (YE), 995 (GY), 1205 (BK), 1499 (PK/LG) or 2086 (RD/LB)
