Some things randomly break or fail and if left long enough, they decide to work again.

One of the quirks of VW ownership!

Switched off the ignition, to ensure the wiper motor was off, and lifted the blade off the window at the next stop.

Turned it on, to let it park, so I could put the blade back on the glass, but it lost it’s intermittent function, and was constantly wiping, with the off function at the dash stalk no longer switching it off either. 

Phil stood behind the bus, and gave me the signal to kill the ignition, when it was in the parked position, so I could leave it there until I got home.

Today’s mission, was to try and sort the issues. First thing to do, was to shorten the blade to the correct length, to clear the window seals. All good. Then I wet the rear window, and switched it on at the stalk. Wiper did a single pass, stopped for the intermittent time, and did another pass…..even switches off again at the stalk switch, so all working again as it should, but I’ve no idea why….

Well worth considering, if mine fails again, or someone else’s fails in the future.

Good info.
