There could also be LEDs like in the radio, or HVAC controls which would also need to be unsoldered and the new soldered in.
You must also take everything apart to get down to the bulbs.
RadioShack sells new 12 volt bulbs, for $1.69 each.
If the digital display is out or half out, it could be cracked solder joints like on my Vibes radio. I hit each joint with my soldering iron and fixed that, I also took the time to replace all the bulbs in the radio since two were out, with the RadioShack bulbs.
Take the dash part and take the DIC out, I can help you from there if you want. The DIC was the only thing I did not remove on my car last weekend when I did my lock switch, heated seat switch, steering wheel control and and HVAC control bulbs.
