rear defroster removal
 
The hatch glass defroster doesn't work on either of my cars, the one on my S worked when I got the car a few years ago but failed shortly after and I can't get it to work again. Anyway, I didn't use it much anyway, is there anyway to remove it? will a razor blade cut that stuff off the glass? Not sure if I really wanna do this yet, just wondering if its an option.

The glass is curved the wrong way to use a razor blade without scratching the glass.

Just fix it. There is some goop you can buy. Use a multimeter in ohm mode and test the circuit or turn it on and use a test light and probe till you find the short. Would be much easer than removing it. GL

Yeah try to fix it. I'm not sure you'd save weight by cutting off the small electrical lines. :)

too bad you don't have that POS LE anymore. You could've tested the razor blade theory on that. :p:

Steel wool maybe?

I would vote to try and fix it. Maybe you could use some of that circuit trace tape stuff they sell at electronics stores for making your own circuit boards? That might work if you need to fix a spot or something.

Ahh forget trying to fix it use your trusty friend the 10lbs sledge and break that sucker out. Naw just kiddin...it would probably be easiest to just fix it. And even if you dont fix it it's not like the defrost lines make that much of a difference in the look anyway. When I got mine I bought the rear window as dark a tint as possible you can't even notice the lines you might want to try that...but then again my windows doesn't got that plastic roll on tint s#%t is cam tinted so I guess I'm just lucky but ya try to fix it first.

As you'll recall I saved all the glass from that car. I don't wanna end up damaging otherwise good glass just to test a theory, I asked here to see if anyone did it. You guys are probably right I'll just leave it. I'll have to put some more time into fixing it, it would be handy now that snow is here.

talk to your local auto glass place and ask them.. but razor blades are flexible, I'd imagine that it would work without damaging the glass...

Nope, trust me, I know from experience, a razor blade will scratch the window. I tried taking tint off my back window of my '79 with a razor blade at first, but it won't work without scratching, so I ended up using a heat gun and steel wool and fantastic to remove the glue.

I have an '80, and the rear lines that connect to the have been off for a long time. What would you suggest to reconnect the wires? Is there some sort of glue that I can use that will hold well and still allow them to work? Thanks in advance for any help.

Steel wool will scratch the glass, too.
Best thing to remove tint film residue is acetone cut with a little naptha to keep it from evaporating too quickly.

I used thermal adhesive (quick siver- adhered a bigger heat sink to my video card) Anything thermal/conductive will work. Radio Shack should have some or local PC store. Local auto parts should too, Im thinking.
