Answer
1. Remove the dust cover from behind the bulb that needs replacement.
2. Unplug the bulb.
3. Taking note of the bulb orientation, unhook the bulb retaining clip from the tang that holds it in place.
4. Remove the bulb.
5. Install the new bulb in the same orientation and clip in place.
6. Reconnect the electrical connector to the bulb.
7. Reinstall the dust cover.

Alternatively, if the bulb is burned out and you have less than 60,000 miles, you should take the car to the dealer and let them do it for free for you.
