Cascadia- How to stop wiper swipe during power on

ive checked it looks dry and fine to me. maybe i should take the whole fuse panel out and check the bottom part from underneath, i have windshield all tight no water comes in, outside applied silicon where water runs down the windshield to plastic cover, checked all grounds. but it definitely connected to water. always after rain

 

possible water intrusion in the Sam chassis module

 

freightliner has special bulletin about this issue. its not related to water intrusion in the Sam modules
