Kinda what I was thinking. Don't get much tip with the soler iron these days and I didn't want to damage the glass, I'd never here the end of it never mind the cost of replacing the glass. Mmmm cold solder , thanks for the tip. Guess i go shoping. Is that the same stuff you brush on to fix damaged defrost lines?

^ sounds like it. I think you may be overly cautious about the 'damaging the glass' thing. I don't think a soldering iron could heat a localized area of window enough to damage or break it.

The hardest part IMO would be soldering upside down like that [img]tongue.gif[/img]

I am overly cautious because I can't aford to replace the window. I had to replace 1 in our old Areostar an number of years ago at an cost of $1 200 ouch! I've seen it done before or at least the finished product so I know/ knew it could be done. Just need to clarify it in my head first. Your right Dukk the upside down work will be the chalange. Thanks guys. This is the kind of feed back that got me here in the first place. And I've never left.

If the polymer is of interest to anyone it is from CAIG and they call it the Circuitwriter Conductive Pen. The part number for parts express is 341-236 if you can not get it locally it runs $10.90 US.

Try the Cold solder that is ad on TV. $29.99 at Canadian Tire. Less heat on the glass.

We do this often. Most auto parts suppliers sell a product specifically for this purpose (Loctite I believe) similar to the "Rear-View Mirror Adhesive" product.

Just a heads up but the solder paste (can. tire has it) you apply and heat with a lighter might work well in this situation....

is the metal pad still on the window
that the connector was soldered too

i think that the cold stuff will not work as the connection will be a high current point and will not stand up

Hey
If the pad is still on the window you will need LOTS of heat to get the window side upto a temperature hot enought to get the solder to wick and make a good connection.
Try using a solder paste available from Active Electronics on 103rd in Edmonton.
Good Luck, J
