Me2. Many of them. Some remorse though. It's inevitable.

Well no joy today. Bronco sat for 4 days while I drove something else. Hit the button and nothing. Held it in for what seemed like a long time and still nothing, rear also. Nothing leaking out, bottle full, pump seems to sound like it is dry. So the question is, where is the check valve it if has one? That is my next place to fiddle with. It did start working when I just got pissed and decided to hold the button and see if the motor burns up first or fluid comes out first. Took about 30 seconds of dry running and then I could hear the motor slow as it got fluid to pump. Worked absolutely flawless for days if I drove it everyday after I drilled the hole in the cap. I run rain-x washer fluid if that matters or not. Time to trace the lines inch by inch and see how it delivers fluid. So far it seems like heat and lack of use are contributing factors. It was almost 100 here for a couple days of the four. It works if I use the Bronco daily but not if I park it for 4 days as a starting point to trace this out. Yes it has a warranty, yes I can bring it in, yes I can try to explain what is happening as it will work fine when you take it in and I will get it back in the exact same condition with unable to duplicate the issue. I figure the deadline now is figure it out before winter. I think on the F-150's there was a problem with the actual spray nozzles when it got colder. The Bronco seems to be the opposite.

And now mine is acting up. Ran it dry then when I filled it a couple days later… barely spits water. I popped the cap off and makes no difference.

When I finally need to take it in for a recall, ( none yet) I’ll get them to look at it. Unless I fix it before then.

Let us know what you find.

Sounds to me like the ultimate bolt on solution is needed-portal washer pumps. Please contact @Kristian@74W for additional information.

All three of mine have done this too. I just hit the pump a few times and it starts spraying on the third or fourth round.

Mine has done this on and off for the past 3 years. It hadn‘t done it for a long time until recently when it did it several times in a few weeks. I, thought it might be a vacuum issue so I popped the cap but it didn’t help. Started working a little while later after driving for a while, worked for several days and then had an issue again today.

The thing I’ve noticed is it seems to dry pump more commonly after filling it up all the way then works more consistently when the tank begins to empty.

Decades ago, Bronco II Manual trans: Chirping sound driving down road with clutch pedal released, stopped with slight pressure. Dealer said it needed clutch and throwout bearing, hundreds of 1984 dollars. Symptoms were reverse of throwout bearing. I researched shop manual, drilled a hole in the bell housing near a clutch fork pivot point dab of grease every 10k or so problem solved.

My boss had a similar Bronco with same problem. He paid for two clutch replacements. He came to me to show him where to drill the hole the third time.

Oof. This exact thing happened on my 2k Tacoma, and the Tacoma forums were full of know-it-alls saying “throwout bearing” to someone else with this issue even after I posted that I had fixed the problem on mine with some white lithium grease on the clutch fork pivot every 15k. Didn’t even have to drill on that one. You just popped a rubber boot out of the housing, greased, and put the boot back in. So easy.

I’m glad to see this isn’t just me. I’ve never ever had a vehicle take so long to spray the windshield. Usually I hit the button and the window is wet before wipers make it across. A bird takes a $hit on the windshield, hit the button, washer fluid coats the window and the poo be gone. With my Bronco I hit the washer button and I get to watch the blades dry cycle 5 times while spreading bird crap like cake icing across my windshield before any washer fluid sort of makes it to the windshield. . WTH.

If a hole in the cap fixes this stupidity I will be a seriously happy camper.

is there a check valve in the system? Maybe under the cowl. I know on the F-150 aluminum trucks a temporary fix was to drill out the check valve to make the washers work.

 

[Ramble_Offroad]

My truck has been doing this. I popped the cap and it really didn’t change anything.

I have had the same experience since the drilling event I added a one way or check valve as I didn't see one anywhere in the windshield portion. It hasn't worked either so I will be replacing the washer motor next.

For those worried about dirt ingress, you can always epoxy a small hose barb in and route some flexible poly tubing away. Or, if you live in a very dusty area like the desert, or South Carolina any time anyone mows their dirt (I swear, one guy mowing his lawn makes a dust cloud visible from miles away), get an airline muffler and pop that on. I used one for the vent on my Moser M9

Well I just went and bought a pump for my 2025. I know it is under warranty but it was $47 so I don't want to hear it blah blah blah. It looks like there is an intake screen (white) that my guess is probably clogged with something from the manufacturing plant or such. I looked up the hose diagram and there is no one way valve after the pump itself or switch that diverts front or rear washer. It appears that if the pump spins one way it goes to the front and the other way spinning it goes to the rear. The white circle seems to be a one way valve on one of the hose fittings. My best guess is that the screen is clogged or the pump impeller has an issue of some kind since mine will spin freely seemingly as if it is empty before eventually drawing washer fluid and working fine for a while. Another guess is that the impeller is not secured to the motor shaft and maybe RainX washer fluid is too slippery. All theories waiting for lab day when I take it apart and get some answers.

More than a few around here think the sun rises and sets on their extended warranty
