We have been having quite the rain here in the NW. After getting in and driving off, then applying the brakes, water poured down from each rear corner of the sunroof. I have no idea how it got there. It wasn't open during the rain yet about a 1/2 ounce of water on each side came pouring out. Any clue as to what might be causing this? Are there drain holes that need to be cleaned? The sunroof was rebuilt a while ago by the PO's mechanic due to it being opened at a high speed and the mangeling of the parts that took place. Is it possible a part was left out of the rebuild?
