Yes Marc, your connector is bad.
Either replace it or cut it off and install terminals straight to the resistor pins with no connector. That's what I did, (and yes, I consider it a HACK job) but I was strapped for time and wanted my blower back. I had two pins welded together (instead of simply mating) inside my connector, leaving nubs on the resistor block.
I have every intention of replacing the connector, but I have more pressing issues at the moment and haven't even looked for the connector yet. It sounds like they are readily available.
