I just today replaced the windshield wiper motor on some advice from a trusted mechanic.This was done to solve the problem of the washer fluid not pumping. I have a new pump in the truck and it does work ,for some reason when i push the switch in to turn on the washer it does not always work and i hear a audible clicking behind the glove box? any help please!!!!

 

I HAVE THE SAME ISSUE !!!!!!!

 

My guess would be a faulty muktifunction switch (turnsignal wiper switch assembly) Ford had many failures with these early switches.
