The reason I found this community (and I'm glad I did) is because my trunk on my 500c wouldn't open. Latch wouldn't get the top to roll up either. I searched high and low. Most places were saying it was the wiring harness (which is a gong show in itself). Before I tackled that I looked some more. Cargurus had a fix to hold the close button 3-5 seconds, open the top, hold the open button 3-5 seconds, close the top and then let it cycle open and closed by itself. Tried it. Voila! I was excited. I think if I'd take it in, they would've charged me $300 to do the same thing. Saved me from taking the wiring apart to look for a short as well. Weird fix, but it worked. :slayer:
