Wipers won't stop

[chimaerachris]

Driving to work this morning the windscreen got a bit dirty so I decided to wash it. Washed fine but then the wipers just continued and wouldn't stop no matter what I did! I had to pull over and disconnect the wiper motor to stop them.
Anyone got any suggestions - could it be a sticky relay?

Could be a relay, or could be the park switch.

Park switch related odds on.

Replaced the park switch about 4 months ago but will check it again

Sorted. The little spring clip had sprung out and the park switch had parted company with the wiper motor. Must have been the potholes!
