Now at winter I noticed that mines audi a4 b5 sedan rear defroster heats only first 3 lines from top, all other doesn`t work. The path of the defroster lines looks good. What would be the problem?

I assume it's like my Avant. Although the traces still appear to be there when viewed from the outside, the actual conductive portion has breaks in it. You can likely find them simply by running your fingers over the lines on the inside. The best repair is replacement of the rear window. Of course that's the most expensive too.

I priced a new Avant rear glass and it was around $800 and that wasn't happening. In my case, over half the lines had multiple breaks a few inches long. So far I've repaired a couple of the grid lines using this product. http://www.frostfighter.com/defroste...d-kit-2100.htm You basically mask off the lines where the breaks occur and paint a new one. It is kind of tricky getting the tape off without pulling the fresh trace off. I used one of those plastic "razor" blades to help. I have no idea how long the repair lasts or how durable it is. It's only been a couple months.
