It is probably easier to pull the fender or inner fender I have heard of
people cutting a acsess hole in the inner fender to get to the blower motor
But I would also check the switch and the blower resistor first and
voltage to the blower
Pulling the fender well isn't really that difficult, it helps to loosen the front fender bolts. There is no way to access the blower motor without taking either the fender or the liner off. Its a terrible design.
