I ran water and weed eater string through them and had zero clogs. Do I need to be more thorough than that or is that sufficient?Look for clogging in the flexible rubber tubes that go through the body, they should be yellow plastic tubes going inside the rear panels and into the floor near the spare tire well. Remove the tubes from the rubber and then remove the rubber tubes to clean them.
The Golf in these years were known for cracks in the sunroof frame, there is a TSB on how to seal it but when those leaked it usually dumped water on the front seat area.
I use Honda shin etsu silicone grease...... a little goes a long way....Is that an actual grease or just the spray?
Yes it came through all of them and I did all 4Did you see the string come out the bottom? Did you do all of them, check if it has front ones also.
The key is keeping the drains clear. Some seem to be more prone to clogging. Climate probably is a factor too - pollen gets in places other things don’t.I had one and it never leaked. If the drains do not plug up, they usually will not leak.
Semantics. A properly designed sunroof will channel water that has gotten past the seal away from the cabin and prevent leakage. I think it would be more appropriate to say sunroofs are not waterproof but water resistant and they prevent leaks.ALL sunroofs leak. My conversation with a fellow GM engineer for body systems once told me that a sunroof in nothing more than an engineered leak. It's how they deal with the water that makes them "dry" or not. All sunroofs have water mgt systems that start with the rubber seals. As water gets past the seals they will run thru the sunroof channels and out the drains. There are normally 4 drains. On cars with the larger 2 piece full lenght roofs there will be a center trim that collects the water and channels it to the sunroof frame and out the drains. As long as your sunroof is properly adjusted, seals are good and drains clear - you won't have any issues.
No they don't. OR-maybe more specifically GM SUNROOFS ALL LEAK.....ALL sunroofs leak.
