fan control switch, and alternator

[Fish Man]

Hey all. Recently my heater fan only would blow on the highest setting. on all other speeds it just wouldnt move any air. I assumed the switch was bad, what else could it be? I got a junkyard switch and put it in, but same issue. Not a huge deal since it still works, but I would like to fix it. Also I put in a remanufactured alternator. I have swapped them before, but they have been remanufactured factory alternators, this one has a different case. Where as the old ones had the plug, the terminal, and a small one or two wire plug, this one has no place for the small plug. What does that do and is it necessary? I hooked it up without and everything seems to be running fine...

you need to replace your resistor on the blower. cheap part $16 and easy to do i just did mine a few weeks ago, should of did it at the beginning of winter. i have no idea about the altenator
