When I purchased the car, they said the windshield washer leaked. I removed the reservoir and checked it and found no leaks. Filled it with water, no leaks. Put it BACK into the vehicle and the next day I checked it and the reservoir is a couple inches low???? I crawled underneath and everything is dry...no sign of a leak. I also checked the hose and that is all dry as well. What the heck?

 

fill it with water and lay a piece of paper just under the Reservoir and let it sit overnight,if Reservoir is empty and the paper has not gotten wet,it's not the Reservoir
