My 2011 rear heated glass is where I cannot see the factory tint is melting

What is your question?

The factory tint is melting inside the glass between the heating strips for defrosting. I cannot use my rear view mirror because I cannot see. When a vehicle is behind me with lights on it look like long lines. I have to use my side mirrors to see what's behind me or checking before passing. How long have you had this problem? Two weeks
