I came across your thread, and I realize it's fairly old, but I have a similar problem with my 2010 Z roadster top. The Top Icon is always on, but the top works fine. The dealer Scanned for codes and they found the code B1777. This code translates to a short in the rear window defrost wiring. I took the car home to see if I can fix the problem. Upon very close scrutiny I found a chafed wire on the drivers side taped to a hinge. I was able to repair the wire however the Top Icon is still on. I saw you wiring schematic, and I noticed that the are 2 20 amp fuses listed and I want to check them to see if they had opened due to the short. However I have no idea where they are physically located. I checked the fuse box next to the battery, nothing. I can't find them. Can anyone tell me where these two fuses are actually located. Thank you all.
