Front Washer Fluid Issue
 

I have a 2015 Ford Expedition. Front wiper fluid is not dispensing.

I have a 2015 Ford Expedition. Front wiper fluid is not dispensing. The back work just fine. Thinking maybe it is a pump issue, I just replaced it. Back still works well, but nothing for the front. When I hit the button the wipers activate, but no pump sounds whatsoever. I checked the fuses I know about, and all seems fine. I also removed the line by the windshield before it gets to the nozzles and nothing comes out there either. I am perplexed as to what this issue is. Anyone have any insight for me, something I may be missing?

I have the exact same problem on my 2017 Expedition. Were you able to fix it? If so, what was the fix?

If you do not hear the washer motor pump run when you select the front washers ,there may be a broken connection between the washer switch and pump. If you do hear it run, look for a hose that may have come off that goes from the washer pump up to the nozzles for the windshield. If all appears OK then remove the hose that goes to the front spray nozzles and activate the pump. Either you will get fluid there or not. If you do the nozzles may be plugged. A little compressed air will usually open them up, blowing from the outside of the nozzle to send the junk back out the open end where the hose is off. If you don't ,check further back to the washer pump to see if the fluid is getting out before going to the nozzles.

Does anyone have a solution for this? I've replaced the switch on the column, I've replaced the motor in the reservoir, the rear is working fine, the wipers run when the button is pushed. The connectors at the column all look good and have been unplugged and inspected, then plugged back in.

This is what I would try.

Verify the ground for the front washer motor.
Apply 12 volts with a jumper wire , to the other terminal of the washer motor. It will run if good and not run if defective.
If that checks out OK, then you need to go back to the wiper motor to determine if it is sending power out to the washer motor when wash is selected.

Let us know what you find, thanks.

The Washer pump is brand new, the multifunction switch on the column is brand new, the fuse is good. The pump runs when rear is commanded, but not when front is commanded. The wipers engage when the front washer button is pressed and held.
Connectors and wires have been inspected, all looks good. So, power and ground at the pump are good.
Honestly, the only piece of the puzzle left, when reviewing the schematics, is the wiper motor assembly. It has an integral front washer relay and some kind of an IC for controlling the wipers and the front washer. I've ordered one and will install when I have some time, probably in a month.

Replaced the front motor. No change. I've checked all relays, swapped relays around, and checked fuses and they're all good.
Now I've ordered the rear motor to see if the internal relay is bad and somehow pulling the circuit down.

Here's the fix

(2017 Ford Expedition Platinum Max, but all of these expeditions have the same fuse/relay setup for the wiper/washer system)

If your front wipers move but no fluid comes out of the front nozzles and there is no noise from washer motor, and your rear wiper moves and fluid does come out of the rear nozzle and you can hear the washer motor running, then the problem may be that there is a relay in the wrong position.

Please note, this solution will probably not help you if you can hear the washer motor running when you press the front wash button.

There are 10 of the exactly same shaped relays in the fuse box under the front hood. 9 of the relays are 'AB' configuration, and 1 of them is 'BA'. The 'BA' relay has 5 prongs while all of the other 9 'AB' relays have 4 prongs. The 'BA' relay is the washer relay; the 5th prong is probably what sends the signal to the washer fluid pump to turn on. The single 'BA' relay has to be in the upper left position (position #1). I found the 'BA' relay to be in the wrong position, someone was probably troubleshooting and thought they were all the same, because they all look the same, except for one detail - the 'BA' doesn't have the small white rectangle like all of the other 'AB' relays.

The rear washer and fluid works with the relays out of position because there is a prong for the rear circuit, but not for the front; it needs the fifth prong to send the opposite polarity to the washer motor to spin in the opposite direction to supply the front nozzles with fluid.

You can confirm that the 'BA' relay goes into the slot #1 by confirming that there are 5 metal contacts compared to 4 on every other slot.

Good luck.

The 'BA' relay goes in position #1.

Confirm the correct position by checking for 5 metal contacts.

Thank you very much for that info.
This info is not found in any shop manual or video and only on a good forum.

I would like to add to that and some folks meaning well will remove a fuse to check it and install it in the adjacent spot and it takes a sharp tech to find that too.

Thanks again.

I have the exact same problem with my 2003 expedition and my relays are 5 prong and no fuses be changed in six years.
