Here's a general procedure:
1. Locate the License Plate Light Assembly: This is located on the rear of the vehicle, above the license plate.
2. Access the Light Assembly: This is the tricky part and varies slightly by model. You'll likely need to do one of the following:
* Twist and Pull: Some Cavaliers have a small plastic cover or retainer clip that you can twist or gently pry loose to access the bulb. Look for small tabs or slots to help you get a grip.
* Remove Screws: Others might have one or two small screws holding the light assembly in place. You'll need a small Phillips head screwdriver for this.
* Push and Release: In some cases, you may need to gently push on the light assembly while pulling it towards you, dislodging it from the clips holding it in place.
3. Remove the Bulb: Once you have access to the light assembly, the bulb itself is usually a simple twist-and-pull operation. Turn the bulb counterclockwise (to the left) and pull it gently out.
4. Install the New Bulb: Carefully insert the new bulb (make sure it's the correct type - check your owner's manual or a parts store for the correct bulb type, commonly a 194 or 168) and twist it clockwise (to the right) to secure it.
5. Reassemble: Put the light assembly back into its housing, secure it with any screws, and snap it back into place if necessary.
6. Test the Light: Turn on your car's lights to make sure the new bulb is working correctly.
Important Considerations:
* Be Gentle: Avoid excessive force when prying or twisting anything. You don't want to break any plastic parts.
* Bulb Type: Use the correct replacement bulb. The owner's manual or a parts store can tell you the correct type. Using an incorrect bulb can lead to overheating or improper light output.
* Safety First: If you are uncomfortable working with your car's lights, take it to a mechanic.
