Just the same ,stick a needle in it !!
That is all I have ever done on any car I have owned, beware that VERY small adjustment makes a big difference to where the spray goes, so it is a case of 'slowly, slowly catchee monkey'.
I fitted 2 x twin spray nozzles to my Civic to replace the built-into scuttle OEM 'Fan' spray nozzles (had to drill a couple of holes and reroute the tubing slightly). Firstly because the washer bottle was not lasting very long and secondly the drivers side OEM 'fan' spray was mostly hitting the parked wiper stem (the new nozzles are higher than the OEM), I tried adjusting the aim of the OEM 'fan' but the difference between hitting the wiper and spraying it all on the roof or following car was 0.0001 of a minute of a degree change in angle (due to shallow angle of windscreen). The resulting 4 jets do a much better job and washer bottle lasts a lot longer between fills.
