If you're talking about the drip rail that goes from the back of the 1/4 glass up and over the windows to the bottom of the front window pillar....it is simply snapped on. To remove, gently but firmly pull out from the bottom. Start at one end and carelully work your way down. The top "hooks" over the metal edge. I used a small screwdriver to coax the trim out then once I had it started, the rest was easy. Not supposed to be glued...but who knows what a PO might have done!! Hope this helps! Good luck.
