The rear defroster on my 2003 Ford Taurus stopped working. I noticed the tab had broken off. Before reattaching I checked the voltage and I have 12 volts between the tabs and through out the defroster grid. I used Permatex® Electrically Conductive Rear Window Defogger Tab Adhesive to attach the tab. I followed the directions concerning the cleaning of the tab and the window. After attaching the tab the rear defroster is still not working. I checked the voltage and current. I am still getting 12 volts between the tabs and 12 volts on the grid. To test I connect one lead of the volt meter to the positive tab and the other to the other tab. To test the grid I attach one lead of the volt meter to the positive tab and run the other lead along each line of the grid and I get 12 volts. The adhesive is not conducting the electric I assume.
Question - How do I remove the adhesive without destroying the window? Is there a way to reattach a new tab to the grid? Can I splice into the grid some how?
