if your local garage wont play ball, its cos they probably dont have an auto electrician, or he knows how tricky it can be to trace these type of problems.
so you have done the obvious, so whats left? wiring..........you dont want to go there, without the right test equipment, so find another garage,,,,, or if it was my car, i would start with changing the wiper opperating arm. if you go down this road, when you fit the new arm, check the connection blocks for signs of heat, this usaly shows as a black colour, if its there clean away the carbon, before fitting the new unit, and test before putting everything back.
i hope this helps you. good luck
