How do I change the blower fan in a ford 2003 supercab
Blower motor in engine compartment passenger firewall area, you may have to remove the cruise control servo to get motor out, very easy and straightforward job, be careful transferring the blower motor wheel over to new motor, remove lockclip first on motor shaft.

If it's the blower motor,the vacuum pump has to be moved out of the way(10 mm bolts) . There are three or four 8mm bolts holding the motor in place. make sure you have power and ground to blower motor before replacing.

Yes, up to the firewall they are pretty much the same
SOURCE: the temperature control does not
I can tell you about my experience on my 1999 F150. I do not believe it is the blower control switch because mine went out and only affected the fan speed. On my truck, in an incident like yours, I could not get a good response from the temperature switch.
I would turn the control and it would hit a stop on both ends, but the temperature would not change to match the switch. What I found is the stem of the temperature control did not turn because the knob cracked behind the switch. There is a half-moon shaped metal clip inside the plastic temperature knob. The clip can spin when the knob is cracked and nothing moves right.
Because the plastic knob has molded stops under the knob, from the drivers point of view, the knob was turning lock to lock. In reality, the stem was not turning. Try taking the knob off and turning the stem with pliers wrapped in cloth to protect the plastic. Then see if the temperature changes.
