Don't open the whole door assembly up...just spray it around onto the weatherstrips or rubber or molding all around. Put a towel across so the silicone doesn't go onto the paint. you need to especially spray it were the bottom of the glass meets the molding. Do it from inside and outside. Have the window up all the way, roll it down, and then up and again. This really helped me, I thought it was the regulator it wasn't it just needed some silicone spray let me know how it works out.
