This morning when I left for work, there was a lot of moisture in the air which naturally left my rear window dewed up on the outside. So I turned the rear defogger button on, and after 10 minutes, every defroster line worked except for one line stretching from the middle of the window to the driver side. I couldn't tell exactly what was wrong with that line as it looked and felt fine to me, and this was my first time using the rear defroster on the G since winter. I also got my windows tinted 2 months ago but I'm not sure if they're to blame for this defroster line problem. Has anyone else had this problem, and if so what did you do about it?

 

They may of disconected itto put the tint on but they should of pluged it back in when done. If thats not it Im not sure.

 

This is a tricky situation. If you had not tinted the window, then the problem could be traced using a multitester. Sometimes breaks in continuity are not visibly evident - caused by some kind of failure in the conductive pigment wires. There are repair kits available for this situation, although their effectiveness (and appearance) may not be suitable. Are you still in the 4/60 warranty?

Unfortunately, since you tinted the window, there is no good way to inspect the problem. And furthermore, reasonable doubt is cast that the tint installer may have damaged the wires when cutting or applying, or that the tint adhesive itself may have degraded the pigment. I doubt you could bring a warranty case. And the tint installer is likely to claim the lines were defective before he applied the tint - unless there is some obvious cut mark that matches the trimming of the tint.

The only perfect solution - if you're not willing just to "let it go", is to replace the entire window glass and have it carefully re-tinted.

Could not have said it better myself.

 

I have 1 line like that too. Maybe it is a Florida option.
