Tools you'll likely need:
* Phillips head screwdriver (possibly a small one)
* Flat head screwdriver (possibly a small one)
* Possibly a small pry tool or trim removal tool (to avoid scratching the paint)
Procedure (Assuming the lens is cracked and only the lens needs replacing):
1. Locate the damaged blinker: Identify the front or rear turn signal assembly that needs replacement.
2. Remove the lens: This is the trickiest part and depends on the design. There are usually small clips or screws holding the lens in place.
* Look for screws: Carefully examine the edges of the lens and the housing. There may be small screws holding the lens onto the housing. Unscrew them.
* Look for clips: If there are no visible screws, the lens is likely held in place by clips. Gently pry the lens away from the housing using a flat-head screwdriver or trim removal tool. Start at one corner and work your way around, applying gentle pressure. Be careful not to break the lens further or damage the housing. You might need to work your way around several small clips. It's usually easier to start near a corner or edge where you can get a good grip with your tool.
* If you're unsure: Consult a repair manual specific to your 1989 Buick Century. A Haynes or Chilton manual will have detailed instructions and diagrams.
3. Replace the lens: Once the old lens is removed, carefully install the new lens. Align the clips or screw holes, and gently snap or screw it into place.
Procedure (If the entire housing is damaged and needs replacing):
1. Disconnect the electrical connector: Before removing the entire housing, you *must* disconnect the electrical connector to the turn signal bulb. This is usually a simple push-and-twist action.
2. Remove the housing: This usually involves unscrewing the housing from the fender or bumper. There might be screws behind the lens you just removed or other securing mechanisms. Again, consult a repair manual for specifics.
3. Install the new housing: After removing the old housing, carefully connect the electrical connector to the new housing. Then, secure the new housing in place using screws or other fasteners.
4. Test the lights: After installing the new lens or housing, turn on your hazard lights and check that the turn signals are working correctly.
Important Considerations:
* Repair Manual: A repair manual specific to your vehicle is highly recommended. It will provide detailed diagrams and instructions for your specific model.
* Safety: Always disconnect the battery before working on the electrical system if you're uncomfortable working with electricity.
* Parts: Ensure you're using the correct replacement parts for your 1989 Buick Century. The auto parts store can help you identify the correct part based on your vehicle's information.
If you're not comfortable performing this repair yourself, it's always best to take your car to a qualified mechanic. They'll have the experience and tools to complete the job safely and efficiently.
