Where is the switch for rear window wiper in a 2003 Yukon Denali?

The rear window wiper switch in a 2003 GMC Yukon Denali is typically located on the left side of the steering column, within easy reach of the driver. It's often a small stalk or lever, similar to the turn signal stalk but usually smaller. It might be integrated with the turn signal stalk itself, or it could be a separate stalk immediately below it.
