I suppose it's possible, but the failures I tend to read about relate more to the unit sticking on one speed. So the blower, in that case, would work but you couldn't slow it down or speed it up.
I think the more common sources of complete lack of power to the blower are the push button panel (easy to eliminate as the problem by testing for power at the appropriate pins laid out in the diagnostics on that site I linked) or the temp control unit.
But run through those tests, try jumping the blower from the push button plug as noted there, see if power is making it through the chain. This will help narrow things down.
You will also be able to jump the plug with the steps noted there to see if the compressor is really seized.
