Hvac blower motor spinning slow

All. I have a 2015 new home. The inside blower motor is not getting up to speed (a recent issue). The relay sounds like its trying, fails to get the motor to speed, stops trying, then repeats the cycle continually. Fan/motor spin freely with no axial thrust or wobble.
I have replaced the relay and the same thing is still happening. Something is preventing the change from "start" to "run".
The compressor runs, flows refrigerant correctly, the evaporator coils are clean /free of ice, and the filter is clean. Mechanic by learned trade, but I'm lost where to look next for electrical issues.
thanks in advance for any help.
