I would like to know if there is a drain in this area? The car has a factory installed sun roof. Does the sun roof have a drain pipe located near this area? I am looking for some advice for a fix. Has anyone had this problem with this model Buick and what was done to fix and clear the leak. This leak creates a puddle on the drivers side floor of the car after a good rain, wetting the carpet, possible rust and mold problems may occur. We love the car and wish to keep it. We are looking forward to some advice for a fix. Thank you, Kathy
