blower just quit working the other night it has a new blower motor and the fuses are good is there not a relay or something like that under the dash that could cause this? the truck is a 2002 f-150 with the V6.I may go thru the fuses again just to see if I missed. Thanks for any help Lee

 

It's called the step resistor. It might be under the passenger side dash/glove box area.

 

Does it run on the highest speed, but not at all on any other speed? If so, it's the resistor pack.

 

It does not run at all on any speed trucks not here now to re-check fues
