How many sunroof drainholes are on a 2007 DTS?
Rain in front passenger floor when it rains hard. I poured water in sunroof track and it ran out front panel just about the glove box. I only found 1 drain hole--on the front driver side in the sunroof track. I could not find any others. Should there be 4?
Yes, there are 4--2 front, 2 back. If you can't see them, it's because they are blocked with debris. Take a pen or wire and gently poke along the front corners on both sides until you find the holes.
