Temp dial works on Low and High

[coopns]

02 Dodge Caravan. The temp dial blower works on low, the next two settings don't work, then the High setting works. So the heat works fine it is the blower that only works on Low and High. What needs to be replaced? I am going to the parts store this week. Is that a DIY'er project or a bit more technical?

Sounds like it could be a switch/relay. I had something like that go bad on my old car. I can't recall what exactly it was that we replaced, but it was a relay of some sort.

The resistor pack [usually mounted on the blower case] is probably bad, or it's connector.

Nope, not a switch/relay. Probably the resistor pack.
