Unhappy Driver & rear passenger floorboards soaking wet...Help!

Can you kind folks advise where I might find info regarding the drain system on the W126 body style?
My beloved 350SDL has water & lots of it coming into the vehicle via the driver side drainage discharge under the windshield. I am specifically looking for a diagram showing the location of said drain tubes from each side of the car & the sunroof (if applicable).
How do you clean out the debris in these tubes so the door drains function again?
A big Texas 'howdy' & 'thank you' for any help you might give!

intrusion source...

Are you positively sure rain enters from the drainage below the windshield and not any higher up?
  1. A-pilar seams
  2. Windshield sealant
  3. (Sunroof drains)
  4. (Cowl pathways)
This may create electrical issues, dry ASAP.
