Hey there, have you tried to ohm out the motor itself? It's possible the internal overloads in the fan motor were opening and closing due to winding break down or bearing drag and finally failed or the windings themselves opened. No continuity across the windings when the motor is cool means a bad motor. Another thing to look at is the relay that turns the fan on. Check the continuity accross the contacts when they close. They can tend to build up dirt and carbon on them. Let me know what you find out. If all looks ok see if you can get an amp draw reading on the motor to see if it is trying to start.

Well try to check the blower fan resistor on your unit... it is possible that this part is now faulty and not working...
