I guess the heat that the copper lines generate is too little when compared to the heat that gets generated when the car is parked under sun. Also, the amount of time you need to run the defogger is not that long enough for the film to get damaged.

Also, I did not quite get your last point on removing the rear glass from the boot to install the tint. I am not quite sure if they actually remove the rear glass from the boot. They just get the measurement from the outside, heat the film to take the rear glass contours and then install it from the inside.

Thanks for the suggestions guys, I guess i'm not the only person facing this problem. Some guys here told me that we can heat up the rear window with a heat gun/ hair dryer and it'll be easier to peel it off. Whereas, a film installer here recommended me to put the car in rain for some time, as when the temp decreases, the gum will loosen up. I somehow tend to believe the first theory though.

The defoggers come with the glass. they cannot be retrofitted.

Yeah fine bro..what will be cost for replacing it.....

Also as a best practise it would be better to put a good film if one wants to install in on the defogger glass. Cheap films are hard to take out due to the gum being used.

Also better to stick to permisible limits of rear films like 70% visibility to avoid removing again because of darker films being against the law.

Nope, not fire. (That would too much of defogging!!!). I am asking if due to usage, you get any discoloration / distortion in the film, where the heating element meets the film.

Guess not, since none have mentioned it so far.

Two ways yes, but the point to be noted is your remark on the risk. The connectivity is very crucial.

For my car (and few others that I had been with when tinting), they removed the whole glass from its location, pasted the tint, waited for some time for it to dry up and then fixed it back. Used to argue at first, but then, when when they say that this is the only way, what other choice do we have.

Will vary from make to make. But then, yes, you will have to REPLACE the entire glass, but hey, you have one for standby (minus the defogger),just in case.

Well, I tried my best to save my Viva's defogger, but failed.

The installer had told me that the defogger will die for sure if I change the rear filming..

I thought I ll be able to remove the film w/o damage and I tried using alcohol, solvents, cleaners and whatnot... but no results...

On the positive, I have come across methods on the net which claims to repair damaged defoggers...

Edit: Would just like to add, No, none of the alcohol went inside me

guys guys i just undid 6 year old tints from my rear windscreen which has defoggers on it without any problem and no damage to the defoggers. let me illustrate my ingenius method lol.
1. look for a small opening in the film at any of the corners of the wind screen, if not create one using a blade by scratching the corner and peel off about 1cm of the film.
2. prepare a solution of soap water in a sprayer. yes! just like how they install the films!
3 spray the solution in the opening and get some grip in the fil and pull gently. you should spray the solution continuously.

do not worry if the film tears, just keep going in the same pace.

this is not a very quick process as you will be peeling in a rate about 1cm per second, but still YOU SAVE THE DEFOGGER!

there you go guys. it worked for me. now someone give it a try and let us all know how it turned out.

oh and remember to place a cloth just below the lower end of the windscreen to soak up the soap solution that flows down.

i had film installed on my indigo from inside only. got it removed and dint damage the defogger.
for starters, get it done on a sunny day. the installer just peeled off the film as usual. and then cleaned the gum with petrol. was a very tedious task but was very well done. one has to be very patient with this. no blade to be used!

i actually can damage the film. i was driving my bosses verna the other day and switched on the defogger. few days later saw that the film is showing bubbles all along the defogger lines.(my boss didnt suspect it being me though )
so i guess no rear sunfilm is the best way if u have defogger.

Car-Dent, the problem may be because of low-quality film. I have two cars with de-foggers and films and there is no such issue.

Why do you want to remove the tint in first place? Is it becos of some darker shade or different color?

My Huper-Optik guys are recommending me to put another layer over the existing layer of the same or darker color! I have first installed a 50% visibility shade but now feel the same inadequate as far as inside privacy is concerned (though no issue about the heat rejection). Wanted to put a darker one, but was suggested to put another one on top of the installed layer. This will result in a darker shade as well as double the heat rejection!

I agree with msaudf's method and it works if done with patience and care. One important point to remember is have the defogger running when this is being done. The combination of soap water and the defogger heat will generate steam and subsequently heat bubbles which will make peeling off the film easier.

Also, older films tend to come off faster and without damaging the defogger. This is because the adhesive would have weakened after repeated exposure to heat-cold cycles and the film itself would've hardened. On newly installed films and high quality films, this is very very tough.

Whatever you do, don't go to your local accessories shop to remove them. Go to a reputed film installer who does exclusively films only, like tintmart, v-kool retailers etc.

+1. A defogger cant be replaced, you have to replace the entire glass.
