Is the left and the right windscreen wiper motor the same? At my Phaeton the left windscreen wiper motor is broken when the screw of the fixing windscreen wiper arm on the windscreen wiper rod on which the screw is tightened. Have still 1 Phaeton as spare part carrier, with which I have already removed the left windscreen wiper motor, and now only the right motor. Therefore the question is whether I have the r to expand real, or if they are different, then I save myself the work best thanks Thomas
