does anyone know how a golf mk4 washer jet system works? does it work on the same principles as a mk2? ie water is forced through the hole system and the chosen jets are electronicaly opened to let the water out . please help.

and will a mk4 wiper/jet fit a mk2? i want my rear window to be smooth but not being able to see out of it would bug me.

cheers

The jets arent electronicly operated. One pump for the front. Fluid is pushed through the pipes and out of the jets.
