Just had windshield replaced and notice the fluid motor would run but no fluid. I'm in Minnesota in winter right now with lots of salt on the roads so this is a serious hazard on the freeway. No joke. I reconnected the hose to the Y splitter, but I noticed the splitter itself was not secured like I saw it should be in a YT video. I recently put the wipers in service mode, and obviously the techs that replaced the windshield did that at least too. My running theory is that the wiper service mode might be what disconnects the hose and or Y splitter. Old post but just putting this out there for posterity.
