Hello and thank you for using Just Answer
the most common cause of blower motor not to run is the blower motor final stage AKA (blower resistor)
you will need a meter to test the final stage

let me know what you find and if you need more help
well the fan did bump at full speed. so thats good and the control heade seemed to change in voltage when tested.
so, I assume it is the endstage resistor. I ordered a new one and we shall see.
thank you for your help, the link to the diagram was extremly helpful in this trouble shooting.
