At some point the instrument cluster light will burn out. Before you decide to change it, make sure that it is not a blown fuse. If you determine that the light is burned out, changing it is not difficult. In order to change the light, the instrument cluster has to be removed. Removing the instrument cluster requires removing the steering wheel. Refer to the article on removing the steering wheel.

Before you do any work on your car it is important that you wear safety glasses, work gloves and dispose of all fluids in a safe manner. Coolant is poisonous and should be treated as such. Animals and small children have been known to die from ingesting coolant. If you have to jack up your car, make sure to use jack stands and chock your wheels as well as apply the parking brake. Protect your eyes, hands and body from fluids, dust and debris while working on your vehicle. If you're working with the electrical system, disconnect the battery before beginning. Always catch fluids in appropriate containers and properly dispose of any fluid waste. Recycle parts, packaging and fluids when possible. Never work on your vehicle if you feel the task is beyond your ability. Always wear eye and hand protection. Disconnect the battery before working on your car.

Once the steering wheel is removed, the instrument cluster can be removed by lifting the top edge.

The light will have two leads.
Figure 3

The light will have two leads. One lead will have a black wire, while the other will have a red, blue and striped wire. 

The bulb can be removed by pulling it out from the lead case.
Figure 4

The bulb can be removed by pulling it out from the lead case. Installing the blub will require you to wear gloves. It is important that you wear clean gloves in order not to transfer skin oils or contaminates to the surface of the bulb. This will help extend the life of the bulb.
Installation of the instrument cluster is the reverse of removal.
