I just had my Bronco in for a service and I logged this complaint as this issue happens to me once in a while. Of course it was working fine when I took my rig inā¦
Hi there, Robert. This windshield washer fluid concern doesnāt sound like something we want you to experience with your Bronco. Could you please send us a PM with your VIN and the name and location of your Ford dealer? I'd be happy to look into how I can assist you on my end.
Iāve had the same issue once a few weeks back. It happened to be a very cold day so I chalked it up to maybe something had frozen up (though I thought washer fluid was designed not to freeze easily). I made sure the reservoir was full, but it just didnāt work the entire way home from the trail. The next day I went to do a full check of the system at the house and it magically worked again.
Mine just stopped working. Only the drivers side. It spurts a tiny bit when I put it on and then stops right away. Passenger and rear are fine.
The standard blue washer fluid freezes quite easily at typical winter temps. During normal winter temps you should use purple or orange winter blend fluids and with the arctic temps we've had the last couple weeks the yellow deicer fluid may be needed. Standard blue fluid is mostly water with a little alcohol and detergent. It will freeze easily overnight and won't thaw out till the engine warms up the engine bay. When you consider the diameter of wiper fluid hoses it doesn't take much for them to freeze.
This is true.

I FOUND THE SOLUTION!
Well... maybe.
Okay, so the first year we had the Bronco, we had this issue several times. Like, at least once every month or two, and most of the time it's hot here, so I doubt the cold/ice has anything to do with it (unless that's another unrelated issue, which it could be). The first couple of times, I thought the tank was low, since you can't see the fluid level visually, and I didn't even realize there's an indicator that comes on when it actually is low. Obviously, that wasn't the problem. And like many of you, this issue comes and goes at random with no clear reason.
Last year (I don't remember exactly when, but it's been several months at least) I started thinking that maybe it has something to do with the washer fluid tank experiencing a vacuum, as if it's not venting properly. So I figured I'd try something:
I drilled a tiny hole, I think about 3/32", in the filler cap. Couldn't do any harm either way. Well, guess what?
We haven't had a single incident of the washer fluid not spraying since then!
Now, does this prove anything? Of course not. It's purely anecdotal evidence, and it could just be coincidence. But we haven't changed anything else, and for some reason we haven't had the issue again.
So if you want to give it a try, it certainly won't hurt anything. You're not going to lose fluid, and it just might work. If anyone here wants to do the same, please post here if you still have a problem afterward. Likewise, if we ever have the issue pop up again on our Bronco, I'll revisit this thread and edit this post...
Good luck!
