Just picked up a 2008 Cts with 44,000 miles on it. I got up today and i noticed the rear headliner was wet. I came to the forums and did numerous searches and found out what might have been the problem. I went to walmart and got weed wacker lines to clean my drain holes, both the front in the sunroof and the 2 back hoses under the trunk lining.
I then did the water test on all drains and the water leaked out front and rear fenders like it was suppose to do. I dried my headliner after all of this. I thought everything was fine until it rained again and the rear passenger side headliner was wet again.
The front and the rear left headliner remains dry, it's only the rear right portion. I unscrewed and pulled down enough liner to see that the hose is properly connected and i noticed no leaks from it. I am lost as to where the water could be coming from.
What are my options and possible pricing to get this sorted. I called the caddy dealership and they quote me around $200 to clean my sunroof drains. I have already done this myself so i have no idea what the issue could be
