Can it cause damage to an electric motor like the ones used in direct drive heating units to spin it fast. I can take an air hose to a blower wheel with an electric motor and blow air onto the wheel. This then causes the wheel and motor to turn and sometimes in the opposite direction of normal. Will this cause damage to the motor?

That motor is an Induction motor.
No, It will not damage the motor.

If the motor is powered, and if you force it to turn faster, slower or even the other way, you will induce opposite currents through the motor.
You will not damage the motor, but if it is driven by an electronic drive, you could damage the driver...
If the motor is not powered, and it has a permanent magnet, you just make it a generator! (And if it still connected to a driver, you could damage the driver again!)

Technically, it does not do that much damage to the motor.
The minimum wear and tear is due to friction because the internal parts does not spin with the blades when not controlled by the electricity.

it doesn't cause any damage to the motor, but i don't understand what you try to do

No not at all, it just seems a bit pointless

That is what we call an alternator in a car...
