Crazy wipers!!?!
 

After some advice please.
I have called 55 V50. Recently it's been doing fine stage things, doors not locking, windows bit working, mirrors etc. One minute they're working the next they're not. We've dropped down the part in passenger footwell and taken out/put back the black blocks and it works ok for a while.
The main issue is today my husband dive the car and the wipers came on full speed. He could not stop them even with the key removed. They then slowed to intermittent, then off completely, and we can't get them back on at all?! Any suggestions would be gratefully received :)

Crazy wipers fixed!!!
