I don’t know if anyone else has come up against this, but I didn’t like the wipers parking on the passenger side. I don’t recall where I got the info from, but I changed it to drivers side parking by turning the gear wheel round. The way to do it is by gently tapping the steel shaft against the plastic gear wheel and they will begin to separate. Then you can turn the wheel round 180 degrees and tap it back and – “hey presto” – there you have it!
