Actually if it runs after a thumping, it just needs cleaning. I mean, you gotta pull it out either way, for cleaning or replacement, but if you're on a budget, it _will_ respond to a good blast of brake cleaner, carb cleaner or what-have-you through the cooling hole(*) and wherever else you can sneak a spray nozzle into. Aim especially for the commutator and brush mounts; try and get visibly shiny contacts as best you can. Then dribble a drop or two of oil onto the shaft bearings and button it all up again.
P.*. Make sure the little rubber cooling-duct elbow doesn't get lost in between removal and replacement. Make sure it'* properly clipped into the hole in the side of the blower housing, and that the other end is plugged onto the evaporator housing where it should be.
