A month or so ago I found that when it rains, water will begin to drip through the dome light in the cabin of my 05 LaCrosse. I suspected that the antenna that is directly above the dome light had a leak. Either the weather stripping is bad or is not flush. I took outdoor silicone and put a nice even bead around the antenna but water is still getting in. The only other idea I have is that the sun roof has a leak somewhere and that is how the water is getting in.


Any other ideas???

Door jam and trunk rear drivers, I don't know exactly as I do not own one, but follow the drawing and you should see it. There is additional information about cleaning these online now that you know what to look for.
