I am currently working on my 1969 Pontiac LeMans. Iím wondering if anyone can offer any assistance on why my windshield washer pump is not working. The wiper motor seems to be working fine. When I press the button for the washer fluid, I can hear the pump making what sounds like a clicking or thumping noise, but no fluid comes through the nozzles.

I installed a new washer pump repair kit, installed new lines, and made sure to clear the nozzles; but still get the same results. I then went a step further & replaced the entire washer pump unit, but still have same results of no fluid.

Can anyone offer advice on what my next steps should be? Thanks
