its a long process,you need a steering wheel puller, once its off take the hazard button assembly out, take the turn signal loose, pull old ignition out, carefully install new one, and reverse procedure and always if u get confused i would highly recomend
a chiltons manual they explain things great

Without taking the tilt mechanism off you can only reach 2 of the 3 bolts. If you use 1/4 in. socket on 1/4 in drive with 6 in extension you can just get at the left bolt. If you remove the tilt spring you can get to the bottom bolt. To remoce tilt spring retainer use standard Phillips.

The switch or the wire harness at the blower motor has gone bad. The highest setting 5 has no resistor, so the blower runs on high but the high current flow ends up burning up the switch's contact on that setting or the resistor wire harness at the blower motor has gone bad. Common would be the switch it self, if the switch is good. Then it's going to be the wire leads at the speed resistor by the blower motor under the glove box by the passenger leg compartment. Keep me posted, be glad to help you get your Sierra running 100% again soon.
