Hi all,

Im out in my 2012 Viano today and the wind screen wash jet is not working; the headlamp wash jet is working.

Does anyone know which fuse is for the screen wash jet? I can not find it in the manual.

Any help much appreciated.

I doubt it .... headlight washers usually use a higher pressure pump
have you checked the pipework hasnt come undone to the screen nozzles....
maybe .... I've had similar when a heated nozzle rotted out & allowed most of the screen wash out under then bonnet rather than through the screen wash nozzles.

Can you hear the pump when trying to wash the screen? A mate of EmilysMum had no screen wash on her car .... the pump was running but no screen wash to the screen. She's been using washing up liquid! Consequently the pump was trying to suck through a load of gunge in the filter.

2014 639 Viano- 651, 5sp Auto. 2009 S211- 646, 5sp Auto.
The reservoir has 3 pumps. I see no individual fuses.
From that I assume each pump is fed from the SAM.

I would unplug, cycle the ignition, and check at the pump for 12 volts when initiated.

From an earlier than 2010 639, but the differences are negligible.
