Pull the weather strip out of the window channel and you will see some small screws.. after you remove those you can gently pry the window channel out; it is held in by a double sided tape or similar material... then you will see about five small screws holding the drip rail trim on. Again, they are also held on with a double sided foam tape, so you must be careful and gently pry the trim from the bottom and roll it towards the top and off the drip rail. (don't lose the screws).
