Thanks again for the help. I located the blown fuse replaced it and it’s all working again.calnorth wrote: ↑Sun May 09, 2021 12:09 pm Am sure OBD tools can't do that. Perhaps a Nissan CONSULT tool might? The latter being at a Nissan dealer.
However, the Body Control Module (BCM) and Light & Rain Sensor (LR) together play a part here. An AUTO selection should give one wipe when no rain present. And Stop
AUTO should stop either by driver selection or go LO speed on LR sensor fault. It appears that BCM is being informed that its raining constantly?
Diagnostics shows:
Front wiper does not stop
AUTO only faults:
• Combination switch
• BCM
• Light & rain sensor (LR)
• Harness between light & rain sensor and BCM
A fault reported by the LR sensor will cause BCM to default to a Fail Safe mode...which places AUTO function working in LO mode. Perhaps its this that you are seeing?
Note that the internal room lamp relay feeds power to the LR sensor. A 10A fuse.
Automatic Wipers always on
