2017 intermittent windshield washer operation

[rlhaberm]

Occasionally my front windshield washer won’t spray. Sometimes it will work after turning off the vehicle and restarting. Other times it will go for days without working, then mysteriously start again. It has done this since I bought it new. I’ve had two dealers try to fix it, but neither can get it replicate. The dealer I bought it from replaced the switch after the 3rd time I took it in, but still have the issue. Both dealers checked fuses wiring, and wire connections. Any ideas anyone???

Does the rear always spray?

If so, I’d suspect some type of obstruction for the front lines.

Try using compressed air to blow into nozzles

Do you have the delayed or rain sense wipers up front? If so try slowly rotating the knob.
