Hi zzzebady.
my roof works completely fine until the last 6 inches or so. This has happened in the past when the temp has been cold. but not its happening in the hot now! I am able to put the roof back up so i am not completely stuck!
If you look at my photos above, you will see the bent metal where the material is held. I believe this is what is causing the problem. I think this is obstructing it at the last bit of the closing.
I have found someone with this problem, and he just bend the bits back and it worked fine, but im a bit anxious to just start bending bits back. I am going to take it to this specialist and let them have a good look at it. They will give it a good lubrication at the same time, and hopefully fix the bent metal.
Nissan said that piece couldnt be replaced, i would need to replace the whole fabric roof if they couldnt fix it, which seem silly, as the roof is spotless.
