1999 Rear Window Defrost

I have a few defrost "bands" that are not working in the middle of my rear window. Is there a way to fix these?

The bands probably have been damaged by something scraping against them. Look closely at each band not working to see if you can see the damage. If you can identify the problem areas there is a repair kit available at most of your aftermarket auto parts stores. Hope this will help. Good Luck.
