windshield washer pump inop - 1989 2.3l

[BuckHilt]

When I push the end of the wiper stalk, the wipers make 2 passes, but no fluid comes out. I replaced the washer pump and still no dice. I've been resurrecting this truck since August and now that pollen season is in full blast I need the washers to work!
Any suggestions?

Do you hear the new pump/washer motor run when you push in the button?

The pump is grounded, and then gets 12volts from the button on multi-function switch, there are no relays or fuses other that the wiper fuse which is OK if wipers come on
"new" doesn't mean pump works, it just means its NEVER EVER been tested

And could be the multi-function switch button is no longer sending that 12v to the pump, but.........I wouldn't expect wipers to come on if that was the case, it would be an unusual failure mode

If you can hear the pump and if washer hasn't worked for a long while then sprayer/nozzles can be clogged if a soapy mixture was last used
Pull off a washer hose in engine bay and check that fluid is pumping out when button is pressed

test the pump outside of the reservoir
if that works check for clogged sprayer lines
if it doesn't, bench test it with another power source/check voltage at the plug when you're pressing the wash lever

edit
Naturally, Ron said it better

Thanks! The pump is now working after kluging a decent ground. Next step is to find a new nozzle. Even usin tip l=cleaners, I couldn't get it to flow. I'll probably replace the hose while I'm at it.

Good work

You can pull it out, soak it in warm water and blow backwards thru it, repeat as needed

Application of compressed air in reverse flow direction cleared it all, and a better ground keeps the pump running. All good!
Thanks to you all for the advice!
