Normal Operation
The smart junction box (SJB) activates the accessory delay relay by grounding the coil side of the relay. The accessory delay relay then provides voltage to the SJB fuse 15 (30A), which in turn provides voltage to circuit 170 (RD/LB) for the window control switches. The LH front window control switch is grounded through circuit 57 (BK).

Possible Causes
- Fuse
- Circuit 170 (RD/LB) open
- Circuit 57 (BK) open
- Accessory delay relay
- LH front window control switch
- SJB
