Fix number 2 for the weekend, with a little help from directions that I found at
http://www.fierostore.com .
So I have been noticing that my car would fog up in the inside the car. The other day I noticed that the seats were soaked, that was enough, I had to do something. So here it goes.
This area is what seems to be the start of the problem. It seems that GM thought it was a good idea to glue the weather seal down in the corners and put no drains in.
I removed the glue substance from the corner of the seal and the roof
Drilled a 3/8" hole in the corner of the roof panel only
You can see here how the hole is tucked under the seal to drain the water off. Now we wait and see if it leaks again. If not the headliner might be next on the repair list.
