Windscreen washer jets are erratic.......

[roygarth]

On my 993 RS they dribble, then shoot over the car then stop on one side and not the other!! Tried cleaning with a needle which hasn't really helped. Is there a DIY fix for this or....?

I think there's a small 'Y' connector in the system below the screen with a rudimentary non-return valve built into it - apparently this often fails causing iffy washer performance.

Could be the cause of your problem.
