Broken heated RW connection
midge - 12/3/10 at 08:59 AM

Hi all,

The connection on my wifes Cherokee has broken off, Jeep want £400 !!!! to fix it (replace the glass). Is there such a thing as conductive super glue??? The adhesive would need to be strong because the tab on the heater element is connected to the wiring via a curly cable which is under tension when the window/door is opened.

Any thoughts would be appreciated.

Cheers

Steve

You might get away with a mechanical joint nearby (i.e. glue a tab to the screen) *then* make the electrical connection (you used to be able to get conductive paint for windscreens, but I don't think it had much strength).

I remember using some 2 part conductive glue a few years back, a bit like araldite but one of the main ingredients was silver.
It was about £40 for a teeny little pack of it (comes in two syringes).
Expensive but better than £400

I had the same prob on my daughter's £500 Saxo. Solution was to (carefully) solder back the connector to make the electrical connection, then cover it with a bit of Araldite to hopefully hold it in place. So far so good

push comes to shove, make your own by filing some copper then mixing it with epoxy - need to add tiny amount of exposy to filings so it has lots of metal.

I sem to recall Maplins selling conductive paint that is used to repair pcb tracks - you may want to use quite a few layers to build it up since large current are involved.

and as ^^^ said, you want to glue the curly wire to reduce the pressure on the connector, soundss like a bad design in the first place.

Maplins sell these - they suggest they are suitable for the job but you may just be wasting £8-£20.

We use Ecobond 56C - it is a silver filled epoxy adhesive. It sticks like S**t to a blanket, and is conductive enough that I can vouch for it being lightning proof!

I work for Pilkington Glass and one of our products is heated rear windows.
The connection is soldered on at the factory so if you carefully abraid the area on the bus bar (The wide part of the element running down the side of the glass) you can solder the connector back on. Obviously cleaning it first. Use standard electrical solder and if the bus bar has a break in it then you should bridge it with some copper say the earth from 13amp flat twin mains cable or you will only have one half of the elements working.

Good ideas, thanks for the suggestions.

i'm sure you can buy some sort of conductive glue from halfords, but i can't remember what its called. my dad spent years looking for some for his car, eventually car got scrapped, and then the stuff appeared.

have a look in halfords

We soldered one on a 309 rear screen with a 100 watt pistol type solder gun. Cleaned it up and tinnned it then re-attached the tab for the wire and it held.
