Can the tint be removed? I just bought this truck and can't see out the back window especially in bad weather. I am going to have to do something

 

I had to remove my tinting or pay a fine about ten years ago.I trashed my grid work for the rear window defogger in the process of removing.I used gentle heat and an ice scraper, I had no problem getting the tinting off but the damage to the heating grids was unavoidable.I wish you better luck.If you have no defogger, use gentle heat (don't overdo it or you will crack the glass) and a razor blade. It will come off with some patience.
