Yea, they're glued. I had a look at those when I was pulling the caps off. Oh and I am not as stupid as to use that type of auto wash. Only a no touch auto wash. Which has only happened twice to this ute. And never again. I dont have one. Might give it a shot with gf's hair blower if she has one? Hmmm. See how some air getting in there works for me. If not Ill pull it out tomorrow arvo and have a go at it.
