fuse?
reset breaker in fuse box?
verify power to blower motor in passenger footwell?
 
If you’re blower fan works (hit it directly with 12v) and your breaker is not tripping then I’d look at the resistor for the fan
 
It could be that its your connector plug on the fan itself. Mine did this and i traced every wire in the circuit and spent hours taking everything apart. The plug was loose on the fan itself. You can get to it without removing anything. its under where the passengers feet would be. Round thing under the dash
