I have a VW Golf MK5 2005 and since buying it second hand the rear windscreen wiper has not worked. The rear washer is working however.
I have read various questions and answers on online forums which all seem to suggest different things. Is there a good logical approach I should take to testing to see if I can locate the issue?
I am not that savvy with cars but I would at least like to have a go at diagnosing the problem before taking it to a garage.
