appears to be behind glove box. seems easy and price seems good...lol so itll be something else.
I seriously don't know what I would do without this forum.

Hello all. Our blower motor only works on 3 and 4. Any ideas?
Common problem when living in the rust belt..
For whatever reason, Ford opted on a lot of trucks to place the resistor pack UNDER THE HOOD near the blower motor..
The problem with the location is the plug/connector to the resistor pack gets a lot moisture.. The result is one or more of the connections on the plug or even the resistor pack end up corroding and eventually fails..
The result is you start losing one or more of the fan speeds with the exception of #4 high fan speed (#4 Fan High bypasses the resistor pack).
Ran into this one on my 2003 F250, lost #2 then #3 speeds..
Pulled the connector to find that the resistor side terminals had rotted completely off..
With some work and several bits of copper wire that I flattened out, I was able to successfully rebuild the resistor pack connections.
If, it ends up not the resistor pack connection then I suspect that your fan control switch may be toast..
Thanks. I'll look under hood and see what I find. I would think if switch goes bad either one speed or all speeds would be down but who knows.

Some resistor packs have an in line thermal fuse that go open.
