Front wipers stopped working?

Front wipers stopped working. Absolute nightmare.

Wipers failed 2-weeks ago on M25 just outside London. Nearly caused an accident. I was driving my wife to airport in torrential rain, heavy traffic and wipers stopped in upright position at 60mph overtaking a truck. Quite scary. Managed to get safely over to hard shoulder.

Thankfully it was daytime although hard shoulder may have been a SMART intermittent lane. Not ideal situation.

Wipers strangely returned to off position but no longer working. Could hear wiper stalk make a clicking sound when activated but wipers not moving. Rain was biblical so unable to continue safely and forced to call for help.

Front windshield washer jets still working. Rear wiper and washer jet still working. All very odd.

Roadside assistance truck came but driver mechanic was unable to get wipers working. He checked fuses, relays and motor. Poor guy was soaked. He kindly dropped wife off at airport and recovered me and car back to Wales. They dropped Outlander off at local Mitsubishi dealer at my request.

Still waiting to be seen…

Hopefully repair will be covered under Mitsubishi Extended Warranty. I’ll report back once dealer has inspected it.

Vehicle inspected by Mitsubishi dealer and they have said the BCM or body control module has failed and requires a replacement.

Mitsubishi Warranty have kindly agreed to cover the repair in full.

Part has been ordered.

I’ll report back once it’s been completed.

Hopefully they've actually traced the connection path, and actually eliminated corrosion or rodent damage before firing the 'parts cannon'.

Wonder what caused it to fail - water ingress?
Where's it located?

IIRC some pug models suffered this type of fault if the windscreen wasn't well bonded since it sat under the LH corner. DIY preventative was to put a plastic bag over it...

Thank God we still have plastic bags! They're trying to eliminate them at all of our local grocery stores ...

This explanation may not be totally accurate.
There's a switch in the wiper motor or its gearbox that allows the wipers to return to the park position when the wipers are turned off by the driver.
So there are two power connections.
One from the driver's wiper switch.
Another permanent feed to the park switch.
So the wiper motor and gearbox are okay as the wipers continued moving to the park position.
The power feed from the driver's wiper switch has gone.

I wonder… hopefully they’ve carried out a full inspection.
