Persistent Windshield Washer Issue

Hey Gents, recently picked up a C7 in good condition. Was really excited and it drives well but I noticed the windshield washer does not work.

I'm fairly mechanically inclined so I followed the steps on other threads and found the pump wasn’t running and swapped it out. Now the pump makes an audible noise when I hold down the windshield washer lever but nothing comes out. There’s definitely fluid in there; maybe the tubes are clogged up but in that case what have some of you done to free them up? What else might it be and what steps should I take?

Thank you!!

Assuming the pump is fully working and the motor is not just turning, can you disconnect the hose and see if water comes out?

Try disconnecting the hoses at the wiper blades to find out if fluid is moving up there.

Good suggestions in the above two posts. Hopefully it is a simple fix.

Found clogged nozzles preventing fluid spray.
Used a small piece of wire to open the nozzles.
