Hi resistance in window conductors

OK, following the advice I received, I tracked both connections to the rear window. There's 12v on the passenger side, on the strip on the window. But as you move the meter probe towards the center of the car on one of the conductor elements, the 12v goes to 0 about 6 inches from the right edge of the window. The drop occurs for about 4 inches, then nothing. On the driver's side, there's ground on the strip on the window edge. Then as you move to the center on one of the elements, the resistance goes up, slowly at first, then in a few inches, it goes up to 10's of thousands of ohms.

This occurs for the 5 or so elements I checked. So it appears the center field of my window defroster is high resistance. I can see no breaks in the traces.

The only thing that comes to mind is buy some conductive paint and try to paint over the strips, several feet for 16 traces on the window.

Any ideas?

Ron
