Multi Function Switch

My wipers have not been working for about 2 months on my 99 blazer. The wiper motor is fine and I have already replaced the wiper pulse circuit. I'm thinking I need to replace the multi function switch. I was just wondering how difficult this was to replace and what exactly I needed to do. If anyone has any suggestions I would really appreciate it.
Thanks!

Ensure the turn signal lever on the multifunction switch is in the neutral position or the OFF position. Remove the steering wheel. Refer to Steering Wheel Replacement . Remove the knee bolster. Refer to Knee Bolster Replacement in Instrument Panel, Gauges and Console. Loosen the steering column bracket nuts. Remove the steering column upper and lower shrouds. Refer to Steering Column Trim Cover Replacement - On Vehicle . Remove the 2 wire harness straps from the steering column wire harness. Remove the connector position assurance (CPA) retainer from the brake transmission shift interlock (BTSI). Disconnect the steering column bulkhead connector from the vehicle wire harness. Disconnect the gray and the black connectors of the switch from the column bulkhead connector. Remove the 2 TORX® head screws from the multifunction switch. Remove the multifunction turn signal/hazard switch.

Thanks, you were a big help, I really appreciate it!
