So I had some help doing this today with some local e90posters! we cleaned it with 91% alcohol, and it ended up getting the crystals off, but looking more smudged overall than before. we put it back together and it seemed to work a little better (the left turn signal now self cancels), but then a few minutes later it went back to its full problematic past.
so im thinking i have to take it apart again and use actual plastic cleaner.
any tips on what to use? meguiars?
did anyone else have this problem?
we didn't resolder the board, btw.
