The right hand drain for the windscreen goes into a drain tube that discharges near the polyV belt. I have always felt this pipe is too short and easily dislodged such that you could get water onto the belts. Worth a check.
Is the black plastic cowling at the bottom of the windscreen damaged?
Yes water could be getting past the spray jet unit, a bit clear mastic could fix that.
I guess you could take the bonnet off, chuck water on the windscreen and you will see where it goes.
I'll need to look in the daylight when I get time. I do think water might be getting in behind the jet just not sure if the drain is out of alignment also.
Thanks!
