2012 GMC Terrain - Sunroof leak

sunroof leak on drivers side

When you open your sunroof there will be rain tubes in the corners. they usually run from the sunroof to the bottom of the car to drain rainwater. over time they can get clogged up causing a buildup and leak in your vehicle. you can try blowing them out with a compressor. or carefully with a long wire. but you do not want to polk a hole in the tube with the wire.
