Just found the problem, water come thru the holes where the small plastic plugs are plugged into the door and soaking the door carpets around the speakers(check those areas when parked outside a rainy day), and then drains thru the trunk buttons and to the driver/passenger panel floor and the water stays there......
the door has been opened for some repair before by previus owner at repair shop and by my suspicion it has not sealed proberly after repair. I have now sealed the membram inside and the plug holes with silicon and sealed electric parts inside.. now it works fine.
