I took tint off my car about two years ago and about two months after that my rear defrost has not worked. The light comes on when you push the button but it seems as though no power is going to the window. On my last stang if you looked real close you could see the which defrost strips were broken, so I look at the ones on my car now and all appear to be fine. Also, my dad used his multimeter and it appeared to find no dead posts. Did he somehow test it wrong or could my problem lie elsewhere. Any suggestions are welcomed.
