Windshield wash not working

Have an assistant turn on the wipers and listen at the reservoir to see if you can hear the pump working.
Disconnect the hose at the pump or at one or both nozzles and turn on the wipers.
If fluid comes out then either the hose or nozzles are clogged. If not check for clogging at reservoir hose.
Otherwise check to see that the electrical connector at the pump is clean and tight and receiving power.
If so then the pump is bad. If not the problem is in the switch, button, lever, whatever or the wiring.
Hope that helps.

Let us know what happens.
