Trane Heat Pump Blower Motor Speed

Hello everyone! I am having trouble with my Trane heat pump model twe049e13fb2. When activating my heater it will only work on manual and not auto. I have replaced the icm board and the motor control ecm. I checked for continuity across the wires of the motor and the resistance was the same. If I turn the stat to auto the blower does not run but the outside unit does. Before this happened, i noticed last year that the motor speed would fluctuate between fast and slow while trying to uae the heat.
