My window wiper stalk seems to have become jammed and I cannot turn off the window wipers?

Does anyone know how to remove it so I can have a look around?

Thanks!

Don't know if this applies to all, but this happened on my 6n and you have to take off the steering wheel by disconnecting the battery for about an hour to stop the air bag going off, then theres two allen key bolts behind, undo them and lift out the airbag and be sooo careful with it, don't knock it or drop it just put it somewhere softly and out the way, then there's a big nut, mark where the top notch of the wheel is so it goes back on straight, undo and lift off, then the two stalks are slotted together so just take out the plugs and lift out, replace or clean, and do in reverse quick easy jobby really, hope that helps!
