The blower motor resistor may be bad and need replacement. I could not find its location. It is probably electronically controled and is part of the circuit board. The only other component other than the motor is the speed controller. Ther eis no information on testnig it. I provided a diagram which shows its locations. The reason there is not any test information is that the system being electroically controlled, all test are circuit board level and would require a special fixture or knowledgeof the board that is not provided by the maufacturer.
The only test I can think of to make sure the blower motor is getting power is to check the connector terminals at the motor. With a multi-meter, check to see if the terminals have 12 volts available to the motor. If it does have power at the terminals the motor needs replacement. Otherwise it is one of the electronic components.
