Hi. Here's 2 pictures from the wheel well. One from inside the wheel well case just above the wheel itself. One from the top near the fuse box in the engine compartment. Yesterday I saw a similar opening in a car like mine. There was no cover but than I saw an other one with a cover. I have presumed they are easy to lose. I suspect the rain, mud and snow spreaded by the left tire near the fuses and relay box is the source of my other problem. No front flasher left nor right.
So what is the purpose of such opening in the wheel well?
Of course I was joking about rain detection!? as I know water and electronic components could be a source of problem.
Tks,
Abel
