I am trying to seal up the roof seams on my 2008 van and noticed some gaps around the windshield, but in order to seal them up, I need to remove that trim piece that runs down the side of the windshield between the A pillar and the glass.
I was actually able to remove the trim piece, but probably not in the "professional" way. I could see that it was held in place with 4 long, white, 2-part clips which ended up being double-stick taped to the A pillar. When I removed the trim piece, I had to pry the taped clip receptacle from the A pillar, then replace the tape when I re-installed. I found some videos on YT that explain it, done by a windshield replacement guy.
The fifth clip was a Y-shaped yellow clip that actually holds the bottom of the trim piece down and even with the A pillar by clipping on the trim piece and hooking under the A pillar edge. That clip went flying down a dark hole between the cab and the quarter panel at the beginning of the removal. I managed to eventually retrieve it by removing the "mud flap" and driver's wheel well, which cost me $20 in body fasteners, BUT the yellow clip cannot be purchased from Honda separately -- it only comes with the replacement trim piece (well over $100).
