With everything plugged in, key on, and switch on high, test at the blower motor. Probe each wire measuring voltage to ground.
Both wires 12 volts-- probably the power transistor. Make sure other functions of the control panel work, such as running the motor that selects the air outlet.
One wire 12 volts, one near zero -- motor is bad.
Both wires zero -- no power from the fuse and relay under the hood.
