Actually I was a little wrong, it's on the firewall, under where the ac lines go through it. It comes out and points to the passenger side of the car, it's only a couple inches long. If you get a socket extension or a stick or something down there you should be able to get dirt or whatever is stuck in it to free up. If it's anything like my friends old Saturn that had the same issue, be prepared for a lot of water to come out. The pic is kind of hard to see but just under and to the right of the ac lines there a rubber dome looking thing, that's the hose. Sent from my SM-G973U using Tapatalk
