Didnt get any responses , so I went to town last Tuesday already

There is actually three slots in the weatherstripping for drainage
One under each pane of glass but there all connected anyways

Started by spraying the inside black slider channel with water bottle waiting for it to drain out - Well that never happened

So I vacuumed the water out , then got out the air hose and went to town with a rubber tipped nozzle

Honestly , I think its been plugged from day one , at the factory
Black RTV - Took some cleaning , peeling back the outside weatherstripping , trying to figure out how everything worked/flowed sort of speak

Filled it back up with water and everything drained out those three slots under the windows

Honestly , really never noticed because I never drive the damn thing , sits in the garage , and then of course that one monsoon with the third brake light gasket leaking , and one thing led to another and another

So far so good - Thanx Guys !!!!!!!!!!!!!!!!!!
