Noticed rear driver light cluster has suddenly some condensation! Not sure if it's cause heavy rain few days ago, but normally in garage and only noticed it a day ago. Anyway does anyne know if easy to remove the actual light cluster light glass,I have removed whole unit? As ithas sort of dried but still watermark which I would like to wipe inside, so wondered if easy to do, with it removed it seems theres a lot of clips to undo? Or is it not worth it?!
