The 2003 Yukon XL contains many buttons on its steering wheel that control the instrument panel display unit and the radio. If any of these buttons begin to malfunction, you should have them repaired as soon as you can. The easiest way to repair broken steering wheel buttons is to simply replace them, as they are cheap and simple to replace. You should expect to spend about an hour replacing the buttons.
Park the Yukon, and open the hood.
Turn off the engine, and unplug the negative ("-") cable from the battery. Allow 10 minutes to pass for the airbags to disengage.
Release the two engaging pins by inserting a crosshead screwdriver into the two pin holes on the rear of the steering wheel.
Remove the steering wheel cover, and unplug the wiring harness of the airbag.
Unplug the wiring harness of the horn cap.
Uninstall the securing bolt holding the steering wheel to the steering shaft.
Lift the steering wheel of the steering shaft. Please note that in order to prevent any damage to the steering wheel or steering shaft, you should use a steering wheel pulling tool. If you do not have one, lift the steering wheel straight up and off the steering shaft, and be very careful not to damage either component.
Remove the two screws behind the steering wheel using a Torx screwdriver.
Lift off the rear plate of the steering wheel in order to access the steering wheel buttons.
Remove the old buttons by prying them out with a slotted screwdriver, and disconnect their wiring harnesses.
Install new buttons by pushing them into the steering wheel, and connecting them to the wiring harnesses.
Reinstall the steering wheel plate and its screws. Reattach the steering wheel and bolt to the steering shaft and reconnect all components and wiring harnesses in the reverse order of removal. Reconnect the negative terminal to the Yukon's battery.
