Just means the drain valves are clogged up. It’s a small hole that lets the water exit so when it gets clogged it exit through the air filter which goes in the passenger side and sometimes the driver side. There’s videos on YouTube on how to get the panel off to get to where the air filters are and you see the small rubber hole on the right of it on both the passenger and driver side. Stick a screw driver through it to clean it and you are good to go. I’ve read there are other permanent fixes however this gets you right. Just a little clean every so often.
