Ok, so the other day when I tried to clean my windshield, I pulled the switch and fluid was sprayed on the windshield. However, I noticed that fluid was also shot out from the bottom of the sprayer and went on the hood. What's the deal with that? It came out from around the bottom of the unit, not a messed up spray angle or anything like that. Also how do I remove the sprayer so that I can inspect it?
