Windshield washer reservoir capacity

[Climber_Diver]

I’m only getting about a half dozen window washes out of my Windshield washer reservoir. I can’t find any specs on the capacity and it’s pretty well hidden in the fender. It just seems very limited.

I first ran low around 3k miles. It fit another whole gallon, even with whatever was still in there.

You have a leak!

Interesting…

There’s no evidence of a leak. Nothing on my garage floor.

That's crazy

Can this be used as a reserve gas tank for 2 doors?

I have the same questions.

Is this full? Empty? I can't see a line.....

no clue.

I have the same problem with the added fun of no fluid going to the rear wiper. I haven’t taken it in to get checked yet but man that big pop up about low washer fluid every time I start gets awfully annoying

Strange.

I was psyched when a full gallon fit. It always annoyed me on all my VWs when a fraction of the bottle had to get stashed for next time. Liters? Ha!

Sounds like some sort of pump issue?

See what happens if you activate it in the garage, pump may be dumping when it's on?

Reason I thought of this is that the fuel pump went out on my Sierra, and leaked when it was on. Hoped it was a cheap fuel line but nope. ***sigh***

Good idea, but still not leaking…

Owners manual just says fill as needed, does not provide a capacity.

I guess it depends on how long you run the washer for you half dozen times.
Barring that, you have already troubleshooted a leak, so that leaves intermittent pump failure (which I assume you hear the pump running, just no fluid coming out), or other reservoir issue (maybe the bottom is filled with sand or jello). When you run out of fluid, how much fluid does it take to refill?

2300 miles in a Minnesota winter, got a whole gallon into it. Worst fucking filler neck design ever.
