So I added some more generic windshield wiper fluid from the local target when I ran out. I test it in the lot, and it works well. A few days later, I try to use it again, and its empty, nothing squirts out. So I add more fluid, and it works again. The system works, but where is the fluid going? I did not see any leaks when I looked under the car. How could the windshield fluid be used up this quickly? Could it be evaporating off?

thanks

 

The hose that is connected to the bottom of the tank may have slipped off. So its probably dripping right out.

 

That's strange. Try putting a cardboard under the car to make sure.

It could only be leaking when you use it, try it out.

Or, it could be leaking when the car's ignition is on.

I'm no mechanic or anything but it's a start.
