I have an '04 Monterey with 3 slides, on the bedroom slide, the front swipe seal is not contacting the side wall, with the slide extended. When the slide is in 4 to 6 inches, the seal contacts the side wall. When extended, the wind and rain water enters through seal. Question, is there a way the get the seal to regain the original contact position, maybe a heat gun? Just hoping I don't have to replace the seal?
