Wiper Washer Help Please!
I have a 1970 with the 5 port system. I just had the wiper/washer motor completely rebuilt/repaired. I installed everything and the wipers work fine but still nothing from the washer pump. Is it possible that my switch is bad? Where do I go from here?
Thanks in advance for any help

Willcox has some good info here that should help you test the switch:

Also, sorry to state the obvious, but are all the lines that carry the water hooked up? (I had a T joint on my 75 that wasn't connected).
And can you test to see whether the lines are blocked - I know your 70 has a different setup to mine so may not be relevant but one test I did was to blow back from the lines coming from the reservoir to see if I could get air bubbles back into the reservoir to show the lines were clear.
I'm sure someone with better 70 knowledge will be along soon

What do you hear when you push the botton in the dash? If you hear the pump working then Tom above is correct! You must prime the washer pump and to do this.. get an extra section of hose.. get you a mouth full of water and pull off the middle hose from the pump.. then put the extra hose on the middle port and force water in there. Sorry.. old school way I suppose but it works.
Now if you hear nothing.. here is how to figure out if the issue is the pump, or switch.
The pump works off two of the wires 14 and 5 show below.
The yellow wire should be hot all the time.. so hook up a test light to the yellow wire and clip on to the blue one at the washer pump. Then push the "Wash" function on the wiper switch. If the you light up.. the wires and switch are fine.
And if you want to test the switch.. here is how:
