self parking switch

[big h h]

Hi guys, i have fitted a new switch now the wipers will not switch off, this is the second switch i have fitted, same problem.
All the wireing is correct, the only thing i can think of is the peg on the switch is not locating , any ideas!.

So do mean the red , yellow and blue wires, as the other side of the switch is a multi plug?

I now have self parking wipers, as the switch was new i tested it as surggested and found it to be ok, i think there was two problems, one the wipers need to be in the middle of the screen and two you need to make sure the spring clip does not move when you push the clip home.
If this had not worked i think it would be a worn cam.
Many thanks to all who helped.
