he has 2003 headlights. if you research this repair you will find that many of these lights coming from 02 and 03 cars cannot be opened by heating the glue, they changed the sealant at some point.
I can still repair the "cannot be opened" angel eye lights with new adjusters. It is involved and takes about 2-3 hours per light and requires a couple special tools I had to develop along the way.
We sell aluminum adjusters for the 01-03 lights at EAC that are far superior to the plastic replacements linked above.
If you are taking the time to fix the problematic plastic adjusters why even consider replacing them with plastic again? Do it once, do it right and forget it.
