Normal Operation
Under normal operation, the LH front power window control switch receives power from the accessory delay relay through circuit CBB38 (GY/BU). The accessory delay relay is integral to the Smart Junction Box (SJB). The LH front power window control switch then supplies voltage to the passenger window control switches through circuit CPW14 (VT/WH).
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- LH front window control switch
- SJB
