Dealer claims A pillar, B Pillar and head liner need to be removed to gain access. $$$$$ has to be simpler solution.

is it leaking inside the vehicle. with the sunroof closed there is what is called a drip bar located at the rear of the sunroof. what this does is catch the water that gets by the sunroof seal. it will direct it to the sides of the roof and out the back drains. you can also sometimes gain access to the drains on the lower rocker panel in
front of each rear wheel. try putting the car on the drive way sloped to the rear. take a small bottle of water and pour it along both sides of the sunroof. you should see the water draining out in front of the rear wheel on that side. if not then it may in fact be plugged. a good shop should be able to gain access to the drain point and using compressed air blow the drains out. hope this helps
