Since you mention smart wheel I assume you have a VIP smart wheel. Here is a link to a trouble shooting guide.
Do the rest of the functions work such as lights, cruise control etc. If they do it might rule out the clock spring.
The motor and drive linkage is all mounted on the inside of the front cap, probably accessible from your generator compartment. You could try and check the motor to see if it is OK.
Second thing I'd do is find you smart wheel controller and pull and reset all the wiring harnesses.
Third thing would be to pull the plastic cover off the steering column and check the wiring harness, there is a coupler that could loosen.
Attached is a parts list for my windshield wiper mechanism, yours may be the same. If not at least it will give you an idea what to look for. I check an the motor is still available, Denso 159100-7370 ~$115
