Alot of Euro cars disable the wipers if the hood switch shows open make sure the hood is closed and /or the switch reads closed.

Your vin is coming up as invalid, however I believe you can monitor hood switch status as previously mentioned through the rear Sam module iirc.

The motor is earthed at the earth…
