One of the 12v supply tabs to the rear screen heater has fallen off,

Dont fancy soldering as I am bound to crack the glass, and super glue or araldite is not conductive. I have seen some "wire glue" but the seller tells me not really suitable for HRW ( heated rear window) , probably due to the heat and/or current ( 20amp?). Also seen some 2 pack conductive glue via Farnel electronics , but dont fancy the £54 price !

Any one got any ideas on how to get the spade connector re-attached to the window?

I've soldered these in the past, so far I haven't cracked any glass. Its always a risk though.

When I've done these I use a gas soldering iron which is equivalent to a 250 watt electric one. My theory goes to heat the joint very quickly so very little heat goes into the surrounding glass. Also, if you heat the 'track' on the glass too much the glue melts and it lifts off.

Where the wire is connected permanently to the metal connector I replaced it with a connector which has a 1.4" blade then crimp the wire onto a new connector and push it on the tab after soldering. My idea here is not to have a thick wire in place which will take heat from the joint. For the last one I did I used solder paste. This worked well as you can use it to hold the tab in place as you heat it. I still used a solder wire just to 'wet' the joint for heat flow.

I don't think any of the conductive paints will work due to the current involved and they're not mechanically strong enough to hold things in place.
If at first you don't succeed, destroy all the evidence and pretend you never tried :lol:

How about some of this if you don't fancy soldering.

If you do solder, bag yourself a flux pen to make the HRW foil nice and clean for soldering.

The glue option looks great, looks like its not available in the UK though. Hopefully that will change soon.
