I AM TRYING TO CLEAR UP A DWI.

You will need to come back to NC for your courtdate.  In order to get the case back on the calendar, you will also need to come back and get served with the order for arest which should have been issued when you missed your courtdate, unless you retain a good traffic/DWI  lawyer, who should be able to get your case back on the calendar without you having to be re-arrested.  They should also negotiate with the District Attorney on your behald to make the rest of the process go smoother for you.  If your case is for trial, a good experienced traffic/DWI attorney can prepare a your case for trial in order to mount a strong defense for you.
