I am having an annoying problem with a leak somewhere in my wiper fluid line. Filling the reservoir only lasts a short time (overnight) until the tank is empty, and the warning light comes on again. There are no obvious signs of a leak that I can see. Ideas?

 

I had this same problem. I thought it was the tank so i replaced that, that did not take care of it. So i replaced the pump that pushes fluid to the headlamp sprayers and that did it.

Hope this helps.

 

That's a thought.
I've removed the fender well to access the tank and traced all the lines and found no leak, so the pump is one of the few options left.
Thanks. It's always something with this car.

 

I know how you feel.

The best way to test the pump is to fill your tank, turn your headlamps ON and run the washer then just watch. Mine had a nice steady stream of fluid.
