Is the carpet or headliner pillars in your 2008-2013 Cadillac CTS getting wet? Have you checked to see if it’s the drain tubes up by your sunroof? Well the video above will show you how to fix them if they need to be repaired.
You can check out Amazon to find Cadillac sunroof drain tubes, roof drain hoses or anything else that is related. If you need to replace the carpet I’m pretty sure they have replacement parts for that too.
