2005 Hyundai Sonata Question: how can i trouble shoot blower motor it is lacking ground

Most likely the blower motor resister. Check for ground going into and out of resister.

You may have 2 problems - the resister and the control head. You should have a signal to resister in any fan setting. If you replace the resister first (cheaper of the two) you should have the blower working on speed 2.
