Rear Defrost Problem

[ADOversa]

So about 2 weeks ago I noticed that 2 of the defroster lines on my back window stopped working. they are about 8 inches away from each other too. Then thismorning when I went out and started the car up I noticed that two more now have stopped working as well, and they are right next to the ones that had already stopped working. I have not touched the back windsheild at all, they are on the inside, and I have not carried anything in the car that touched the back window, and the lines are intact. Anyone else have a similar problem?

The dealer suggested I put my ohmmeter on to check for resistence, but I don't want to do anything to it until they look at it.

This dealer has already screwed me over once so far on something that SHOULD have been covered by warranty. I don't want to give them and reason/oppurtunity to do it again, but it sounds like that is exactly what will happen again. I called and explained the problem, they told me it would not be covered by warranty. I was too nice about it the first time I had a problem, and I let it go. My mistake. This time I have already called Nissan Canada to give them a rundown on the situation so far and the history, and just make them aware of whats going on now.
