Pinpoint Test 1: All Power Windows Are Inoperative
PINPOINT TEST 1: 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 (G/L) for the window control switches. The master window adjust switch is grounded through circuit (B/GY).
Possible Causes
- Circuit breaker
- Wiring, terminals or connectors
- Accessory delay relay
- Master window adjust switch
- SJB
