What a convoluted way of doing things!Ozvtr wrote: ↑Thu Nov 25, 2021 12:14 am Have the wipers stopped at a random point on the windscreen or parked at the bottom of the windscreen.
It's a bit of a bazar arrangement. The "wiper power enable" relay sits in the BSM but is controlled directly by a wire from the BSI! The high speed/low speed relay sits in the BSM but is controlled through the CAN BUS from the BSI! Power comes from the battery to the fuse, through the power enable relay to the speed relay and then to the wiper motor. Most of the time ground is provided by the BSI. Power AND ground are switched by relays.
Have you pulled the connectors out of the BSM and looked for corrosion?
I will check for corrosion today. I only checked the fuses yesterday, and nothing else.
Do you meant these connectors in the engine bay fuse box?
