Tools You'll Need:
* New turn signal bulb: Make sure you get the correct bulb type. Your owner's manual or a parts store can tell you the correct bulb number.
* Small flathead screwdriver (possibly): Some bulbs are held in by a retaining clip.
* Gloves (optional): To protect your hands from getting greasy.
General Steps (with variations depending on location):
1. Locate the bulb: Open the hood (for front turn signals) or access the taillight assembly (for rear turn signals). The front turn signals are usually located within the headlight assembly. The rear turn signals are part of the taillight assembly.
2. Access the bulb: This is where things vary most:
* Front Turn Signals: You might need to remove the entire headlight assembly, or there might be access through a panel behind the headlight. Some models allow access from the back of the headlight assembly once the front is removed. Consult your owner's manual. You may need to disconnect the wiring harness and possibly unbolt the assembly from the vehicle.
* Rear Turn Signals: Usually, you'll need to access the taillight assembly. This often involves removing screws or clips holding the taillight in place. Once the taillight is removed, the bulb socket will be visible.
3. Remove the old bulb: This usually involves twisting the bulb socket (usually a quarter-turn) or gently pulling it out after releasing a retaining clip. Be careful not to break the socket.
4. Install the new bulb: Carefully insert the new bulb into the socket, making sure it's seated correctly. Twist it to lock it into place.
5. Reassemble: Put everything back together – the taillight assembly or headlight assembly, reconnect any wiring harnesses, etc. Make sure all screws and clips are secure.
6. Test: Turn on your hazard lights or turn signals to make sure the new bulb is working.
Important Considerations:
* Owner's Manual: Your owner's manual is the best resource for specific instructions on removing and replacing bulbs for your 1999 Buick LeSabre. It will show you exactly where the bulbs are located and how to access them.
* Bulb Type: Make sure you buy the correct replacement bulb. Getting the wrong type can cause problems.
* Safety: Always disconnect the negative battery cable before working on any electrical components in your vehicle. This is a crucial safety precaution to avoid short circuits or shocks.
If you're uncomfortable working on your car yourself, it's best to take it to a qualified mechanic. They'll have the tools and expertise to do the job safely and efficiently.
