The truck is a 1989 Dodge Dakota 3.9. Blower motor does not work at any speed so I wasn't thinking the problem was the resistor. But the connector looks like this:

If the resistor connector is so corroded, could that stop even the high speed from operating? It looks bad, even the connector is corroded and melted. I do have power coming to the resistor.

If there is no bare steel showing where theresistor attaches, then there can be no current flow. If there is still good steel under the corrosion, clean it off and attach the reisitor again to see if it works. Have you measured the resistance value? It should be in a very low value around 0.5 to 5 ohms. If it is open, try Radio Shack or an electric motor house for a replacement.

And I figured I'd buy a new resistor and end up at the junkyard for the connector, never had an idea I could get that new. Thanks for the connector links.
I guess I'll be adding the resistor and wiring connector to my next rockauto order.

There isn't much to try and clean, it's almost corroded away to nothing!
