The resister is located in the blower housing just left of the blower. If your dash is similar to the one in our '15 Windsport you may be able to reach the resister from the bottom of the dash on the passenger side. It will have a wire connector in the center and two small screws, (one on each side), that attach it to the housing. Unscrew those and it drops right out. The blower system is probably by Evans, not Ford.
