Any suggestions out there on why my wiper washer on 63 swc won't pump the fluid? The unit was sent in and the repair shop says it works fine. I can hear the washer pump as the button is pushed. Checked the tube for any obstruction. I even tried priming it with a funnel and some elevation to the inlet tube, to no avail.

I have the exact same probem. I was told to Prime it. Fill the hose with fluid. Let me know how that works. My car is in storage so I have to wait until April.

After rebuilding my pump, I had to resort to sucking on one of the outlet tubes to the spray nozzel while blocking the other outlet tube to get it to prime. Might try a small syringe filled with water to push water into the inlet side of the pump.

You may want to double check the valve plate. It only takes the smallest particle of dirt or hard water scale to make any of the valves not seal correctly. All three valves have to seal correctly or the pump won't work.

I managed to pressure fluid through the lines to test those. So there was no blockage. After disassembling the pump I found the diaphram was collapsed. But it also appears to be missing a rubber seal in the end with three rings. This seats the inlet and outlet orifices. So will order the parts and see if that solves it.
