Footstep had water sloshing around in it!! :*water gets in when left on certain slopes/directions. Any clues where it may get in. should it drain out also? Door seal seams fine. No abuse -low mileage 04 SWB model.
Remove the footstep liner and clear the two drain holes, i would also pour some old engine oil down too, it will coat up the inside and may stop that water from rusting your ride from the inside out. :ILU:
i had this prob mate, top left hand of screen was leaking, check behind the sound proof in pass foot well. mine was soaked!! had screen re-sealed,cost me 45 bucks-problem solved T: hope this helps fella
