I got my 323 blower motor resistor and noticed its almost an exact match for the plug configuration. It has a blue wire coming in instead of the second spade for a jumper. As I looked at it I thought, why don't I just pull a spade from my old one, put in this one and solder the connection to it so the jumper works for it. That way I have all brand new resistors and less work to get this fixed cause I know swapping the resistor wire will have a high risk of messing up the other resistors on the old one.

I will be doing this today and will post up with results here. Details will go into my other dormant AC thread I've had up since a year ago as I finish redoing my HVAC. Thanks for the inspiration to do this from this thread.

Heres the 323 pics to compare:





And heres where the blue wire connects:

 

The blank slot in the 323 doesn't go thru. I'll have to open up that slot somehow. I tried heating the prong up red hot and poking it thru but that didn't work well yet. Just had lunch hour to play with it. Tonight I can maybe break out some drills or dremels to get it done. Other than that, pulling the prong out of the old resistor pack is easy. Just push in a tab and then pull it out, carefully.

 

So I was able to heat the prong connector I removed from the old resistor pack and push enough through to open the slot up. The upper part of the old prong widens a bit and wouldn't go all the way down to get the needed length for the plug to connect. So I took my trusty dremel out and shaved down the outer edges and was able to push the prong all the way in.

Here is pic of the removed prong and not how theres a step up in the width about half way up.



I pushed it into the new 323 resistor pack



I then soldered a wire across to the connector on that same side near it. Installed it into my blower housing, Then tested to make sure I had 3 speeds and all progressively higher as I went from low to high. Seems to work like a charm.

So now I have all new resistor wires that are unmolested and should last another 20 years.

 

I know this is a year later but thanks to Ta-Aikah and the others in this thread for inspiring me to try to do this.

 

Shame the initial idea isn't quite as available anymore, but good work finding an alternative!

Glad to see I've given back to the forum at least a little of what I've gotten from it.
