window defroster

My window defroster does not work for any lines, I did have my windows tinted this summer. I could see a few lines broken but not all? There are two terminals on passenger side, one on drivers side and one on top (not sure if that is antenna?). Does anyone know what voltges I should see at terminals, or what impedance (ohms) I should have between terminals? Any testing advice appreciated, I did a search but results were not detailed as I hoped. Thanks
 


the lines that are small and tighter together are the radio antenna. the fat lines are the defrosters, so make sure the 2 wires are clipped on still or not broken.

also check the fuse box if the def lights not coming on when you hit the button. if you have a light, my regal does.
 
The light on defrost button is on and fuses check out. There are different voltages at all tabs and this seems confusing. The tint guy had told me he cuts and lays everything out on exterior glass- his work is near perfect. I can see one line getting damaged but for all not to work seems odd. The tabs seem secure but maybe I better pull rear deck panel off and check wiring for shorts or breaks. ??
