To find it, you need to:
1. Identify your taillight assembly: Look at your taillights. Do they have a single bulb (usually a larger one) or two separate bulbs (one for brake/turn, one for running light)? This is the crucial first step.
2. Access the taillight housing: You'll typically need to access the taillights from the inside of the trunk. There are usually screws or clips holding the taillight assembly in place. Consult a repair manual (Chilton or Haynes) for your specific year and model for precise instructions. This is very important to avoid damage.
3. Locate the brake light bulb:
* Single-bulb assembly: The larger bulb is likely the one for brake/turn signal, and it will often have multiple filaments. The repair manual will show a diagram confirming the bulb's position and function.
* Dual-bulb assembly: One bulb will be solely for the brake lights. Again, the repair manual is essential to correctly identify the brake light bulb.
Without a repair manual specific to your 1979 Chevy Malibu, I cannot give you a precise location. Repair manuals provide diagrams and clear instructions to avoid damaging your car. You can find these manuals online or at most auto parts stores.
