4ks washer question.

[Roger D. Albert]

Hi all,

I'm down to fix a few nagging electrical problems on my old '86 4ks and
thought I'd solicit some opinions and any possible btdts before spending
hours going over electrical diagrams (I've spent a bit already)

Basically, my washer pump doesn't  If I apply power to the motor
directly, she spins right up and douses things.

I pulled the steering wheel and lower column shroud to get access to the
washer switch.  The contact definitely makes (when pulling back on the
wiper lever) as it properly activates the wipers for a cycle or two. 
Somewhere, the signal is not getting to the pump.  Anyone seen this
exact symptom before and/or know of a common cause for this wipers-work
but pump-doesn't symptom.

thanks in advance
