These inside door handles are an absolute nightmare. They are the same on the full size trucks. You did remove the water deflector. You have to drill out the rivets. I have in the past removed the complete window,regulator and chanal just to make life easier on the trucks. Here is the link for the water deflector.Good luck, hope it works out for you.
Front Side Door Water Deflector Replacement Removal Procedure
Important: Water deflectors seal the inner panel. Water deflectors prevent water from entering into the body. A strip of adhesive between the deflector and the door secures the deflector.
Important: When replacing deflectors which have been peeled back or removed, the adhesive on the door and the deflector from the factory will usually be adequate in order to re-adhere the deflector to the door. If additional adhesive is required, use a small amount of weatherstrip adhesive, such as GM P/N 12345096, Canadian P/N 993365, or an equivalent adhesive. If the deflector was separated at a perforation, use a cloth reinforced tape with a strong adhesive in order to secure the piece together. Replace the deflector if the deflector is too badly damaged to provide a proper seal.
