There are two breathers in the engine compartment just to the left rear side of the battery. One is attached to a small hose and the other to a larger one. The small one is in the back of the larger one. Both are attached together by a clip. The small one in the back is spring loaded and moves up and down with finger pressure. The one in the front does not move. It seems it is stuck in the down position? What do you see on yours? Mine is a Trail with KDSS.
