Have bought a brand new corolla with 4000km on clock, recently noticed that washer nozzle was not spraying at all. Was able to take it out thorough its clips and cleaned it and installed it back. I realized that in-fact it is spraying but spray direction is down, hitting the plastic part and water goes down. I have inspected the unit but don?t have a clue how to adjust the directions as its not like previous rolls. Your help will be very helpful.
