As mentioned , check for loose or bad connections going back to the switch. And check the switch turned on under a no load and under load conditions.

Voltage at the plug at the pump, correct?
Check harness of pump for continuity, if you have it the pump is suspect

I can't help with the electrical problem, but do you need me to swing by to help with the air filter?

That's a pretty lame offer, at least you could offer to change the blinker fluid too.

[Ah Pook]

I already filled the blinker fluid. Air filters are over rated. All the do is get dirty. Don't need 'em.

Looks like I will be chasing wire, when the weather gets better.

Ok, pulled up the wiring diagram and took a quick look, do the wipers do the 5 stroke wipe when you actuate the front washer switch (ignition on, of course) with the new pump motor installed ?

Bob said "5 stroke wipe".

Nevermind, reread your first post, your problem is after the switch and at or after the common point where the washer switch actuates the wipers and feeds power to the washer pump.

And to BP, it doesn't take much to put your mind in the gutter, does it ?

Actuate the wipers and they will wipe and there is current at the pump plug but only when the the pump is not plugged in. Plug in the pump and nothing happens. No wiper. No current. Nothing.

Hopefully you are a slim small person, you will need to measure input and output voltage at the connector on the bottom of the steering column most likely the switch/ multifunction board under the steering wheel airbag. Be extra careful ! Shorting the wrong terminals in that connector could deploy the airbag.
Get a chiltons manual with wiring diagrams and disconnect the battery, wait 15 minutes, then disconnect the airbag circuit per the manual then reconnect the battery to troubleshoot electrical problems under the dashboard.
