Wiper spray not working

I tested the washer plug for voltage I get OL when I press the washer button. I do get some washer fluid coming out of the sprayers but it's very very little.

Disconnect the hose near the nozzle and check for flow. Could be the nozzle is plugged up or the pump is weak.

Try using some white vinegar in case someone used regular tap water in the washer reservoir.

Also, someone may have taken a sharp seamstress pin or safety pin and wallowed out the washer jet hole. If so, you can get replacements from the Ford dealer. I had the same problem you had and someone thought that it was a good idea to wallow the head of each out sprayer.
I replaced them both and no problems. I think it cost $6 for 2.

Rodents like to chew on the hose too. It's 1/4" OD tubing.

Check your hoses under the sprayers. Mine were cracked and leaking fluid. Then I replaced those and then it ruptured the elbow at the washer tank.

What should the voltage be at the plug when you press the washer button?

12 volts.

I love how nobody bothered to read that you got OL when testing with the meter

I skimmed past the OL part because of this statement. To me, it sounded like the pump was working but not getting much volume.

So Did I...

"OL" and reading there wasn't much volume from the sprayers totally suggested the Pump was working.....
