Not serviceable unless replaced.
I understand it needs replacing my question is how do I achieve this replacement? Please. Is there a cheat-sheet I can follow?
Only thing I can think of is maybe try www.alldatadiy.com or maybe look at YouTube videos and search and look for rear view mirror replacement to get some kind of an idea.
Unfortunately it's an assembly, no parts available to repair it. Try www.alldatadiy.com for instructions.
