Hey, I know this is a few years old, but hoping someone could help me out!

I have a question about the rear defrost fix....I thought I had fixed it... and followed your directions perfectly, but for whatever reason it still is not working.

Here is what I have done..

1. Cleaned connections with rubbing alcohol

2. Sodered wires back to the connection as suggested (green wire on the left, black wire on the right)

3. i put the tab connectors back on the rear defrost and it doesn't work.

Here is what I have tested...
1. The relay - ensured that the relay is working great
2. I have used a voltmeter and tested the wires, the green wire is giving about 11.5 volts and the black wire is not giving anything...(what is the black wire for?)
3. Before putting the tab connectors on the rear window. I test the voltage of the connector. The connector to the green wire is showing 11.5 volts...the other connections is still not showing any volts, but I am assuming that this is for the radio?

As soon as I put the connection on the tab to the rear window, the voltage drops to about .3 volts and it does not heat up rear window...would anyone know why!? Bad module maybe?
