Cleaned out the washer jets today as one was completely blocked. Having a pig of a job lining them up right so they spray correctly through the 2 holes in the wiper blade cover (what a crap design)

 

Do you do it with a pin and the cover in place? Also should the 2 jets spray at the same position - say 2 o'clock for example or are they set differently?

I have only managed to get them to spray through the holes. Not much more adjustment is possible- but a pin/needle would work. I rarely need to use them anyway.

I had the same issue and gave up.

 

Ended up buying a new nozzle for £2. It fired through the holes perfectly!
