* The reservoir: Holding the washer fluid.
* The pump: Pushing the fluid through the lines.
* The lines: Delivering the fluid to the nozzles.
* The nozzles: Spraying the fluid onto the windshield.
Replacing the windshield involves removing the old one and installing a new one, but it doesn't usually require disconnecting or altering any part of the washer system. The technician might temporarily disconnect the lines to avoid getting fluid on the new windshield during installation, but they're reconnected afterward. If the washers *don't* work after a windshield replacement, there's likely a problem with the system unrelated to the windshield change itself — a kinked line, a disconnected nozzle, a faulty pump, or a problem with the fluid reservoir.
