General Steps (Expect Variations):
1. Trunk Access: Open the trunk of your Cadillac Eldorado.
2. Locate the Light Assembly: The license plate light assembly is typically located on the inside of the trunk lid, near the license plate itself. It might be a single unit or two separate units, one for each side of the plate. Look for a small cover or access panel. It might be a simple push-in cover or held by small screws (usually Phillips head).
3. Remove the Cover/Access Panel: Carefully remove the cover or access panel to expose the bulb. Be gentle to avoid breaking any clips. You might need a small flat-head screwdriver to pry it loose if it's stuck.
4. Replace the Bulb: Once the cover is removed, you should see the bulb. It's usually a standard size (often 194 or similar). Gently twist the old bulb counter-clockwise to remove it. Insert the new bulb, twisting it clockwise to secure. Make sure it's seated properly.
5. Reassemble: Replace the cover or access panel, ensuring it's securely fastened.
6. Test the Light: Close the trunk and test the new bulb to ensure it's working correctly.
Troubleshooting:
* Stuck Cover: If the cover is stuck, try gently prying it loose with a small, flat-head screwdriver. Work slowly and carefully to avoid breaking the plastic. A little lubricant might help.
* Bulb Type: If you're unsure of the bulb type, take the old bulb to an auto parts store for a replacement.
* Wiring Issues: If the new bulb doesn't work, check the wiring to make sure there are no broken connections. This is less common, but possible.
Important Note: Before starting, consider taking pictures of the process before you disassemble anything. This will help you remember how to put it back together.
