HVAC fan switch or resistor ????

The lowest setting is blowing at the 2nd setting speed. That heat blowing on my throttle foot all the time sucks! All other settings (2-4) work as they should.
I'm thinking resistor but I'm second guessing myself on the switch.
Imagine the lowest resistor setting blew and now it's running off the next resistor setting Ö. regardless of switch position. Does that make any sense?
Any experience with this?

Recap: Low speed setting blows at second speed level. All other settings good.

It's been along time since I replaced mine. That does sound like the typical culprit. As I recall:

The Resistor reduces the fan speed on lower settings. So if the lower speeds don't work, it's very suspect.

That's what mine did. Bought a replacement resistor at NAPA for $19 and it's all good. Been about 4 years since mine went bad.
