Hi,

 

When I drive my car, the sunroof blind always starts to slide open an inch or two.

I slide it back forward to close it and it still slides back again after a few accelerations.

 

Am I missing a trim or something ?

 

Everything looks like it’s there and it’s done this since day one.

 

 

Saloon? I have the same issue. It even moves half way during the daily commute to work. 

I assume you mean with the sunroof open? Mine does this, mainly at highway speeds, and physics are too blame. The only way to stop it would be to somehow increase the sliding resistance of the blind such that the flow of air over it can no longer pull it back.

Mine has been doing this since new as well   this is without the sunroof open.

Only moves a few cm's over a couple of days but still a bit annoying!
