It is difficult to remove the nozzle without damaging its latches. Therefore, we simply pull out the old nozzle with pliers, after removing the hose put on its fitting under the windshield frame. It is more convenient to perform this work in the warm season - the soft hose is removed more easily. In winter, before you take off (or wear) hose, warm it with your hand.
We put a new nozzle, directing the jet at the glass. We make sure that both antennae-latch snap into place.
Holding the nozzle, we put a supply hose on it from below.
We also replace the second nozzle.
