If you have to turn the wheel RIGHT NOW, you could try a little trick we used when doing police towing etc, you push down and towards direction you want to turn it, at the same time with your left hand at about the 7 oclock position of wheel. Then with your right fist, pound away from you on the top of steering wheel repeatedly and it should bump around for you. Did this all the time, and fords were the most cooperative. I know it's hack, but it may work.
