Check the connections on the E-series vans blower resister. The resister and wiring have a bypass to send full voltage to the blower motor. a loose connection here will cause the motor to not run on high.
it needs a blower motor resistor to make the fan settings work.If you replace the Blower MOTOR Resistor it should resolve the problem.
Assuming you're talking about the blower motor, because the blower motor resistor is faulty, and needs to be replaced. On the high setting, it doesn't go through the resistor - on the other settings, it does.

the resistor has melted the variable settings. Replace resistor under passenger dash.
The blower motor resister for an Acura Legend drops the voltage to the blower motor. This is what allows the motor to run slower for the medium and low settings.
A malfunctioning blower motor resistor will cause the blower motor not to work. When the resistor is bad the blower motors will not turn on.
Blower motor resistor has failed
The Resistor is located on the outside of the blower motor. Have to remove the blower from under the glovebox to get to it. The Resistor is located on the outside of the blower motor. Have to remove the blower from under the glovebox to get to it.
The blower motor fan cools the resistor so the resistor is usually located close to the blower.
