Sunroof drain blockage
 

I am 90% sure that I have the blocked sunroof drain leaking inside car problem that has been referenced a few times on the board.

BUT, as far as I can tell, nobody ever tells us how to clear the blockage.

Sooooo, anyone have any secret tips on clearing the blockage?

Do I have to pull the headliner/assembly?

Wire; air; small mammal?

All tips considered and appreciated.

I think Raggot, the gerbil, is too big for this job.

Pulling the headliner is the right way to do the job, but sneaking/snaking a semi-rigid tube to each corner and using compressed air will work - IF you can see the drain openings. The downside to that method is too much air can blow the drain hose(s) off of the nipples and cause a nasty stain on your headliner the next time it rains.

Removing the headliner really isn't that difficult, just remove everything - visors, mirror, grab handles, etc. and pop the trim loose. Fold the front seats forward and slide it out through the right-hand door.

Once you get the head liner out, what do you do Beav? Can you see the hoses then? :confused: :confused:

Yup, you can see it all once the headliner is removed. Even if the sunroof need to be removed for really nasty accumulations, it only requires loosening four nuts. I can't imagine it taking anyone more than 2-4 hours, including a couple breaks. 'Sticking with it' time probably around 1-1 1/2 hours.
