I hear the pump but no spray. I tried blowing air thru lines, then pulled back the wheel well liner and there is a small black unit w/elec.connection attached to the bottom of res. What is it??
I believe the pump is the unit to the inboard of the filler tube up in the eng. compartment. /ubbthreads/images/graemlins/confused.gif
The res. is full and no water came out of the unit on the bottom when I removerd the rubber hose from it.
Thanks for any help,
Don

u may have to replace your washer nozzles. it is a common problem on the Super Duty

Thanks, Bosmack,
There is no water coming from the reservoir to get to the nozzles.
I am wondering if the unit attached to the bottom of the reservoir is the problem.

Probably one of the things your seeing is the sensor? (We have a WS fluid light,, don't we? /ubbthreads/images/graemlins/shrug.gif /ubbthreads/images/graemlins/phoney.gif) Cant recall if we do or not,, /ubbthreads/images/graemlins/tongue.gif /ubbthreads/images/graemlins/crazy.gif

I found the problem with a suggestion from another forum. He said if I tap on that unit on the bottom of the reservoir it may free up whatever is keeping it from flowing and it did. I pushed on the washer control and the windshield washer worked. However, in my original post I thought the washer pump was that unit located right next to the filler tube on top. Wrong...It sure looks like it could be, it has the rubber hoses going in one side and out the other, sure fooled me, apparently that is a vacuum pump of some kind.
