Brent, there's no connection between the steering wheel and the blower motor. The blower motor does need to be installed in exactly the right position because it can contact the inside of the housing. There's very little margin for error. I've seen slightly wobbly blower "cages" cause exactly the problem you mention. If you really have found a good mechanic, he won't have a problem re-checking his work if, as you imply, the noise started immediately following the repair. Don't worry about "alienating" him either. If he is the real deal, he'll worry about alienating you. Good luck
