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.

Hi Aly This G wagon gets its supply voltage for the front wiper motor from the engine fuse box at fuse 111 which is a 30amp fuse. At the wiper motor you are looking for a red/black wire from the fuse box. is this powered? there is also control of the wipers at the front sam box on a LIN Bus at pin 4 on the wiper motor connector which is a black/yellow wire. The motor is earthed at the earth…
