Ok here's my problem...

I have a 2004 BA XL Falcon Ute. When I flick up the left toggle for the wiper blade to cycle once it will only move if I keep hold of the toggle.

As everyone knows you should only have to hold it for a second and it does its thing by itself.

Has anyone else had a similar problem or know how to fix this???

Hope that all made sense. Any help would be greatly appreciated cause this is really starting to piss me off!
