Rear defroster won't work need diagnosing assistance

[steppinthrax]

I have a 99 Camry LE. I noticed when it started getting cold the rear defroster didn’t work. I would push the button and it would light (indicator), but I can tell it doesn’t work. I have the Factory Service Manual. I went though the diagnostics but the only thing it leads me is something is wrong with the wiring from the relay (switch side) to the actual defroster coil.

I’ve done the following

1. Tested the switch (works)
2. Tested the relay (works clicks when switch pushed)
3. Pulled off molding on rear window and checked coil. Coil shows resistance and works, no damaged lines.

The I pulled off the wires that run to the defroster coil. I’m getting no voltage to the defroster coil. Which tells me something is wrong with the wiring that leads to the defroster coil.

Does anyone know any other ideas?

Even if the relay is clicking, It may not be providing a closed circuit. Test voltage from the relay.
