I am having water leak into one headlight every carwash. It takes a week or two to go away. So this is not simple condensation.
I think I may have found out how. I clean the wheel well on the passenger (right) side and there is a missing cover in the inner fender liner. I have attached a pictures below.
Have I got the right spot?
I think it is part 8 or more likely part 9 on this diagram.
Is this flap for changing headlight bulbs?? I am guessing the pressure water jets get water into the headlight assembly.
