There is a blower motor resistor module in the circuit between the selctor switch and the blower motor. The problem is either going to be 1. the switch, 2. the wire for low speed between the switch and resistor or 3. the resistor.
I am not sure to be honest on its physical location. I am looking at the electrical prints. It should have 3 wires going to it, 1. Low speed - Red w/ Black stripe, 2. Med speed -Blue w/ Red stripe, 3. High speed and straight to motor - Black w/ yellow stripe.
Someone will probably chime in on where it is located. I bet Dennis or Beavis might know.

The resistor is located on the side of the plenum under the dash. It looks alike a black piece of fiber board about two inches by two inches with some wires connected to it. Two screws hold it in and the back side once you remove it looks like a spring.

Then I suggest you learn how the system works.
The resistor shown above ..RESISTS current to the motor thus Slowing it down.
The problemis with the switch in LOW speed.. Highest resistance.
Therefore, there is a problem with the HIGH resistance coil of the resistor.
as medium (less resistance) speed and HIGH ( NO Resistance) speed still work.
A fuse is a protection device .. if there is too much draw on a circuit then the fuse blows creating an open circuit and NO POWER is delivered to that system.
Therefore it can't be a fuse as power is still getting to the motor.
The circuit requires a GROUND to complete the circuit.
No Ground..... No motor spin at any switch position
