Was it working before you changed your controls,check your blower motor maybe it's gone bad.

Need more info on what was wrong to begin with.
If the fan wasn't working to begin with check under the hood at the back side of fan to make sure the wiring is in place.
If that looks ok then start with a test light and try it at the switch. Check to see if you have power to the fan switch.
