But then I thought about rusting out the gutter as the water never drained. So I took the block out. I even put screen door mesh in that opening to keep the tree gack out.

So now into the shop. Ready to drop some Big $$$. My headliner has a brown stain in that area. It cleans up with the "Right Stuff" Cleaner but I and tired of dealing with it. The only bad part is that The side airbag also gets wet tucked up in the headliner. Fark It....Into the shop she goes.

Feel your frustration with this, to bad GM has allowed let this to slide for so long. embarrassing for them. You may have a new business opportunity if your mechanic finds a solution, I'll drive anywhere and pay the going price to have this fixed..
