BMW Repair: Air Bag warning light and Door seals, passenger doors, regulator repair

Question
I have a 2001 330i.  The last 7 are FK46177.  I recently got in the car and drove to the store, when I came out the air bag light was on.  I have no idea what the issue may be.  I haven't gotten it checked out, any thoughts?
 I've also noticed over the past few months when it rains, then becomes sunny.  I get condensation inside the car. I've looked for leaks and check for wetness inside the car.  There doesn't seem to be anything leaking.  The only thing out of the ordinary is that in the door tray (behind the seal, but not in the car) on both the driver and passenger doors water will accumulate.  It doesn't get inside the car, but I don't think it should be there.  

Answer
James, you will need to have the Restraint system faults read out because there can be any number or faults that will turn that light on. The water that runs down the windows and into the door will drain at the bottom of the door outside the seal (normal). The vapor barrier that seals the door cavities is probably torn or loose from a regulator repair in the past is allowing water vapor into the interior. Remove the door panels and make sure those vapor barriers are completely sealed.
