I have an 04 f150 and recently my blower or fan does not work on settings 1 and 2. 1 went out first and not 2 does not work. Any suggestions on if the switch is shot or blower? Thanks

 

There is a resister set on the ground side of the wiring on the blower circuit. One or more of the resisters will burn out. Causing those speeds not to work. I'm not exactly sure where it is on your model, but on the older ones it is close to the glove compartment. Just race the ground wire from the blower motor to find it.
