Hope some of you clever people can help. My rear wiper stopped working a while ago. Read the posts on here so promptly took the motor off to give it a good clean up. Tried it again and no dice. So bought a used motor from a Mk6 Fiesta to cannabilise for parts. Before doing it, I thought I'd plug the new motor in to check. Nothing. Wired it up to a 12v battery on the bench to check it was working (it was). Left scratching my head.

I've checked the relay in the boot which seems fine. The only weirdness is that I'm only getting 0.12v at both the relay (pin 4) and the plug (middle pin) when the wiper cycle comes on. Anyone seen this before, or know what else I could try to resolve this problem.

Thanks.
