The front-view camera washer nozzle may be leaking washer fluid on some 2022-2023 Silverado 1500 and Sierra 1500 models. (Fig. 7)

Service Information or the Electronic Parts Catalog does not show that there is a one-way check valve built into the windshield washer hose that connects to the washer pump. (Fig. 8) The check valve is designed to prevent washer fluid from leaking.

If no other cause is found, replace the windshield washer hose, which will include a new check valve.
