Blower motor for A/C & Heat not working properly. Motor still works. Air is coming through at speed it's supposed to. Problem is noise and vibration. Once turned on the whole dash and steering wheel shake. Could this just be the wheel itself, instead of the whole motor and wheel assembly?

You want to make sure the steering wheel isn't actually loose, and address that if it is. You may be getting vibration from a bad blower motor, but I think it is more likely the A/C compressor is turning on and causing the engine to shake. This may be from a bad motor mount or something with the compressor. If the engine isn't running and you turn on the fan, does the dash and steering wheel shake?

Even when the engine is off the dash and steering wheel are shaking. Steering wheel is secure, not loose. I never thought of a compressor issue. Is my best bet just to take the blower motor out? What symptoms should I be looking for if the motor itself is bad?

If this happens when the engine is off, then this is likely the blower motor. If you find the blower motor, then put your hand on the motor housing as it's running, you will feel the vibrations really strong if that is the problem.

Found the problem. Took the blower motor out and found a mouse and lived his last days in my car. He was in my blower wheel and his nest was above. So it was nasty to clean but saved me $70 on a new blower motor. Thank you for you help :)

You may hace somthinf occluding the fan barrel or you need a new fan/motor unit. Easy fix to replace. Blower is under the cabin filter at the center of the firewall under the hood. 2 pring plug/; fan motor and barrell just slide right in. Cost: about 250.00 if you doo it yourself.
