Test A: All Power Windows Are Inoperative

PINPOINT TEST A: ALL POWER WINDOWS ARE INOPERATIVE

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 circuit breaker 47 (30A), which in turn provides voltage to circuit CBP47 (GN/BU) for the window control switches. The LH front window control switch is grounded through circuit GD149 (BK/GY).

This pinpoint test is intended to diagnose the following:
- Circuit breaker
- Wiring, terminals or connectors
- Accessory delay relay
- LH front window control switch
- SJB
