Moin, Moin,
My sunroof dains seems to be clogged or broken. I have a wet passenger backseat. The headliner and the c-pillar trim are also affected.
Is there any easy way to repair/clean them. Or do I have to take everything apart?
Regards
Sundroof Drains

Re: Sundroof Drains
It's been a while, but I think if you take the c-pillar cover off, the drain tube will be readily visible and you can check if it's clogged or disconnected.

Re: Sundroof Drains
Moin, Moin,
Yesterday I tryied to open the c-pillar. But how to do it without breaking it? In my TS all plasic parts are bold on, easy to remove. I didn't find any screws, or even a way to start deesembling. Everything is quite tight and make cracking noises if I try to pull it off.
What did I wrong? Is there a step direction I have to use? Or am I just to much afraid of brake something? No screws is suspicious.

Someone else will have to chime in. I don't really know.

Re: Sundroof Drains
Never torn into an 87-91 gen, but yes all the 92+ Bonnevilles that I've worked on have plastic clips and retainers holding trim together. No screws. It is indeed very difficult to remove brittle plastic without breaking it. There is not a lot of information out there either.

Re: Sundroof Drains
There is nothing more annoying than having water in the car.
Removing the c-pillar trim only does not work
I removed some of the plastics, the clips were working pretty good for 30 years.
They were so tight, that I broke one trim part. But nobody will see it...
You can see the pipe. But it is not a clear one. So because it was already loosend, pulled down the sky trim and coud see the pipe plugged to the roof.
I unplugged the pipe and cleaned it. I used a welding wire with a bended end. It was clogged with grease from the well greased sunroof
Handling the wet sky and pillar trim without breaking it, is not easy!
Since then I'm trieing to dry the car. But it was so rainy the last days, and I need to use the bonneville as daily...
But I think the roof is not the only reason for the water in my car.
