The metal reciprocating arm with the rubber insert popped off from the motor's pin when overloaded by snow. The tip of the flat metal arm also got bent but I was able to straighten it in situ. It was impossible to access to push it back on so the wiper motor had to come off. First remove the plastic covers to expose the nuts and remove the wiper arms (with the wiper blades)
Next, open the hood and locate the rain plate. This is a metal plate situated below the windscreen and is almost the full width of the windscreen. On this metal plate there is a plastic cover which is pushed against the windscreen. Remove the two plastic buttons at either side of this plastic cover and pull it out. When re-fitting this plastic cover, make sure it snaps firmly into position, against the windscreen. Once this is removed, it will reveal 5 screws holding the metal rain plate (two more screws are already visible). Remove all 7 using a 30 size t30 torx screwdriver. There is just one more bolt which goes vertically up into the heater matrix. It secures the heater matrix to the metal plate. Remove this also and the whole metal rain plate will come out with the wiper motor and linkages all attached to the plate. On the way, you will also need to remove the washer tubes, wiper motor electrical connector etc. When re-fitting, make sure the wiper linkages are at the park position because space is very tight.
