2007 Ducato with an aftermarket wiper setup after previous linkages got too sloppy. Everytime i turn the key i get a single wipe (and usually need to give a quick squirt on a dry day to save the motor somewhat). Apart from the single wipe on turning on the ignition the wipers work as expected in all modes. I expect it is connected to the B1021 code.

Any idea why this may occur/solutions?

On a side note:
The B1023 error is also a bit of a mystery to me but predates the wiper motor change and the above issue, however the wash and wipe works perfectly also so any ideas on this would be good.

Cheers, Paul

Not sure if it will help but many moons ago my father had a similar problem on an old Hilman car he had. It turned out to be a bad earth connection........
