after finding the horrors after removing my carpet, when the car comes back from the body shop, i want to turn my attention to rear sunroof drains i know how to exit them from the boot, but can i get to drains were they connect to the roof just by taking out the lights and prying the headliner back ? i dont really want to remove the whole headliner from the car. Ive been searching posts on rot and this a very likely place for tin worm and ive had wet carpet in the rear before i just want check it all sound under there

anyone ?

Actually I would like to know too if there is a way to remove the rear part of the headliner back to access the rear sunroof drains? I pressed against mine and it sounds like cornflakes....aka rust.
