I have a 2004 F-150 and for the last year after every rain storm both my driver side and my passenger side wiring harness channel fills with water. After work yesterday I came home and checked out that area and found more water so I used my shop vac and sucked out the water and then put a little fan against my brake pedal t o dry the area. Before I went to bed a checked it again and it was dry. Once I woke up this morning I new it rained last night so I thought it would be still dry. So when I opened up my door and loooked down were the wiring goes threw that channel I saw that it was filled up with water again. Hopefully someone may have a suggestion about what I should do. ??????????????????????
