Myself i would find a wiring diagram an see where the power comes from ! You can find free wiring diagrams here http://www.bbbind.com/free_tsb.html Enter your vehicle info. year , make , model an engine . Under system click on HVAC - heating ,ventilation an A/C . under subsystem click on HVAC controls ,then click on the search button .Two links will pop up , click on them one at a time . Is your system manual or automatic ? Automatic has a blower motor speed controller . The manual has a blower motor resistor assembly . You can find videos on youtube on how to test blower electrical circuits !
Well i would test to see if there is power to the unit, is there is then it could be a resister if not it could be a fuse or resistor. i would start in the fuse panel.
