Water leak, wet headlining.

[Rs31markie]

Hi all
Just wondering if anyone has had similar problems, my headlining is wet just where the A pillar trim and head lining meet, it’s only on the passenger side. I don’t think it’s the windscreen leaking as it’s too far back, it’s almost underneath the roof rack trim, does that have grommets that secure it which could have perished?

Thanks for any suggestions
