How to fix Sunroof Drain Pipe in A Pillar..?

[Tricky Dicky]

Further to my previous post 'Water in A Pillar', I've now found that there must be a split in the sunroof drain tube running down the A pillar...   How the heck do I fix this ?

hard way is to remove headlining to gain access to tube and pull it out of the a pillar or a bit easier would be to get a length of tubing of a smaller diameter and push it down the inside of the existing tube from the corner of the sunroof.

I would go belts and braces and remove the headlining... if only to get eyes on the actual cause

Ho hum. I'll be busy tomorrow then  .

Problem Found - dodgy O ring at sunroof end of outlet pipe. Changed it, hoping it'll be okay now, although it's not the tightest fit... might have to resort to silicone sealant. Have left the corner of the headlining loose and the A pillar cover off to let it all dry out. Thanks for the guidance  .
