So hears the deal every since i got the car the rear defroster never worked, and the other day it was pouring and it would of been nice to see out my back window. The light comes on when you push the button and you hear a click down by the fuse box, and i checked the fuse under the dash and the hood one looked good too. I removed the clips from both sides and tested them for power with it on and got nothing. Hears the thing tho the previous owner had tint on and removed it at one time, and I'm pretty sure he used a razor blade because all my lines in the back window are orange there are no breaks in them there just orange? would that make it not work because i have no idea whats wrong
