i just kind of noticed, with all the snow and all, that on the rear window, ther is a defroster look right near the top, but in my car, id does not work. While the regular grid that goes all the way across the window works fine. I noticed that some of the grid had flaked off, so I went to NAPA and bought a kit to help replace it, which actually worked great. however, i went to go test it on some freshly fallen snow, and it still wouldn't work. So i took out a tester and tested the grid to see if it was getting power, and there wasn't anything even coming out of the wires. I was wondering if this is something that is common in reattas, and if there is some way to fix this. Thanks.
