Often lights under a dash or indicators just blow out bulbs. If more than one thing isn't lighting and are centralized check fuses to see if its blown. Bulb or fuse. IMHO. MIGHT be a sensor on tranny too. Hope not.
Here's a video with detaile dinstrauctions and other people's fuse questions. New fuses?

what is best is the schematic.

If the horn works with the alarm button but not with the steering wheel horn pad the problem is most likely in the contacts beneath the steering wheel. This requires pulling the steering wheel and repairing the contacts. If this vehicle has an air bag in the steering wheel make sure to deactivate the airbag circuit before pulling the steering wheel.
The switch has to be replaced, the bulbs are not serviced seperately. On some of the vehicles, you could pull the the switch out far enough to access the connector and change it from the front, but be careful, if there is not enough slack in the harness, the steering wheel has to come off, along with the rear cover on the wheel, to get enough slack in the harness to remove the switches. This was a design change around 2004 or 2005.
These steering wheel lights are usually sealed units, much like radio backlights. They can be repaired, but they have to be sent out for service, which means removal of the steering wheel, etc.
Speak to your dealer about the cost of such a service, your options, and their recommendations.
If this is the lights for the switches in the steering wheel, these are LED's. The switches are made in such a way that it is prudent to replace the switch rather than try to take it apart and replace the LED. The switches are relatively inexpensive and are very easy to replace. While the LED's are rather inexpensive, the time that it would take to get the switch apart, replace the LED and then attempt to put it all back together is not worth the twenty to thirty bucks for a new switch.
I have replaced three of the four that are in my steering wheel. The hardest part to the whole thing is making the wiring connection in the back of the switch for the two large ones on the center crossbar. My fingers aren't quite slim enough to make the connection easily. I found using a pair of hemostats or some type of thin clamp with a handle works very well.
