Welcome
After checking fuses this would be the next place I would look.
Be sure to post the results, or ask for more help if this don't fit your problem. The location of the resister is described at the bottom of the first post

I have checked the fuses and switched that one with one that I know works and it still didn't work. We have checked if the fan still works by attaching an outside source and it does. I have looked at a few other forums and many of them think it is the blower relay. I have a new relay but we can't locate it. If anyone knows where that relay is please let me know

Your owners manual will show you where the relay is. If you don't have the manual, you can download it from Fleet Ford.

I believe the power goes from the switch to the blower resistor then to the fan. You can find the blower resistor by looking from the floor up just behind the glove box.
Look for something like this:

Locate the blower motor connector. One lead should be battery voltage whenever the blower should be operating. The other lead should measure anywhere from zero when the switch is in HIGH to several volts when in lower speed settings.
If you have battery voltage on one lead but zero volts in all switch settings on the other, the blower motor is bad.
If neither lead has power when it should, check the blower motor relay located in Aux relay box #4.
