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.
You can determine if your blower resistor is faulty by checking for inconsistent fan speeds or if the blower motor only works on certain settings (usually high speed). Additionally, if the blower motor doesn't operate at all or if there’s a burning smell, it could indicate a bad resistor. Testing the resistor with a multimeter for continuity can also confirm whether it’s functioning properly. If these signs are present, replacing the blower resistor is often necessary.
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.
To replace the blower motor resistor on a 2001 Hyundai XG300, first disconnect the negative battery terminal to ensure safety. Then, locate the blower motor resistor, which is typically found near the blower motor under the dashboard on the passenger side. Remove any necessary panels for access, disconnect the wiring harness, and unbolt the resistor from its mounting. Install the new resistor by reversing the steps, reconnect the wiring, and test the blower settings to ensure proper function.
To change the blower motor resistor on a 1993 Dodge Dynasty, first disconnect the battery to ensure safety. Locate the blower motor resistor, which is typically found near the blower motor itself, under the dashboard on the passenger side. Remove the electrical connector and unscrew the mounting screws to take out the old resistor. Install the new resistor in reverse order, reconnect the electrical connector, and test the blower settings before reassembling any panels.
