Normal Operation
Under normal operation, the LH front power window control switch receives power through circuit 1499 (PK/LG), which is the delayed accessory relay output from the smart junction. The delayed accessory relay is integral to the smart junction box (SJB). The LH front power window control switch is grounded to the chassis through circuit 1205 (BK).

Possible Causes
- Circuit 1499 (PK/LG) open
- Circuit 1205 (BK) open
- LH front window control switch
- SJB
