2007 Altima - Partial Failure of Rear Window Defroster

If it's abrasion damage from something being rubbed over the elements they won't pay or replace under warranty.

How would I now if it is abrasion damage? I just bought the car from a rental car agency and have no idea what happened before I had it.

Do you see any broken elements. Does your car also have the radio antenna in the back window? They may be the top elements that are not the defroster and therefore not heating the glass..

The radio antenna elements at the top of the glass are not broken and I know that they don't heat the glass. It is the 10 elements of the defroster below the antenna that are broken.

They are broken, or just not work? If you can see breaks in the elements, they can be fixed by you. Go to an auto store and get a repair kit. You paint a the special conductive compound on the broken parts thereby making the elements whole again.

It is hard to describe: I can see the lines all across the class. When I run my finger over the lines, I can feel that there is a break in the conductive material of 1/2 to 1 inch. So I would think that painting the lines over those parts that are "broken" should fixit.
