Windscreen washers not operating correctly.

It could also be a leak. This would allow a low pressure, feeble flow at the jet, since the leak is robbing the system of pressure. Park on a dry pavement and run the wash for 20-30 seconds. Then get out and look for signs of a leak on or under the vehicle. One weak spot prone to tubing failure is near the hood hinge on the passenger side. If no leak is apparent, then a clogged jet would be the next possibility. Be very gentle when probing to clean the jet. Hope that helps.

Get yourself a small gauge/thin piece of wire. Poke the jet holes with the wire until they spray like they used to. If you have an air compressor you can also blow through the sprayer with compressed air after poking them with the wire and they should be good as new. If that doesn't work you might have a blockage in the line at the one-way valve or at the pump in the washer tank.
