It's a workhorse chassis, take it to Chevy/GMC. The turn signal switch is above the tilt, so its wires run down through the tilt. They are supposed to be held in place, but must have gotten loose and pinched, causing them to ground (short) and blow the fuse. If the wheel has no airbag in it, you might want to try it yourself. Otherwise, take that beauty in.
