However, the general steps are usually similar:
1. Locate the fasteners: Look carefully around the edges of the taillight assembly. These fasteners might be:
* Screws: These are often Phillips head or Torx.
* Clips/Retainers: These are plastic clips that snap into place. You may need a small flathead screwdriver or trim tool to gently pry them loose.
* Nuts: Less common, but possible.
2. Remove the fasteners: Carefully remove all screws, clips, or nuts. Work slowly and gently to avoid breaking any plastic clips.
3. Gently separate the cover: Once all fasteners are removed, the taillight cover *should* pull away from the body. There might be some resistance; gently work it loose. If it feels stuck, double-check that all fasteners are removed and look for any hidden clips. Pulling too hard can break the cover or damage the vehicle.
4. Disconnect the electrical connectors: Once the cover is loose, carefully disconnect the wiring harness connected to the taillight. Usually, these are simple push-in connectors.
To get specific instructions, you need to provide the exact model and body style of your 1990 Chevy. A quick online search for "[Your Chevy Model] 1990 taillight removal" or checking a repair manual specific to your year and model will likely provide diagrams and detailed instructions. YouTube videos are also a great resource.
Important Note: If you're unsure about any step, it's best to consult a repair manual or a qualified mechanic to avoid damaging your vehicle.
