1. Access from Underneath the Car:
* Locate the hood release cable: This is the most common method. Get under the car, ideally on ramps or jack stands for safety. Locate the hood release cable where it connects to the latch mechanism under the hood. You'll likely find it near the center of the car, possibly towards the front. The cable might be easily visible or hidden behind some underbody panels.
* Try to manipulate the cable: You can try to pull the cable with pliers or your hand. It might be stiff or rusted, so use caution. If it moves, it might pop the hood.
* If the cable is broken: If the cable is snapped, you may need to try the next steps.
2. Access from the Engine Compartment (if partially open):
* If there's a tiny gap: If the hood is slightly ajar, you might be able to use a sturdy, flat object like a long, thin pry bar or a screwdriver (wrapped in cloth to prevent scratching) to gently pry the hood open wider. Work slowly and carefully to avoid damaging the hood or surrounding components. Insert the tool between the hood and the grille, being extremely cautious not to damage the paint or the radiator.
3. More Involved Methods (Requires More Mechanical Skill):
* Removing the grille: This is a more involved process and may require some disassembly. Removing the grille might give you access to the latch mechanism directly. Consult a repair manual for your specific model to understand the grille removal process. This is not recommended for someone without mechanical experience.
* Accessing the latch from inside the engine bay (if possible): If you can see any parts of the latch mechanism from the inside of the engine bay (even with the hood closed), you might be able to manipulate it with tools. This approach is highly dependent on the specific design of your car's hood latch.
Important Considerations:
* Safety First: Always use jack stands if working under the car. Never work under a vehicle supported only by a jack.
* Repair Manual: A repair manual specific to your 1989 Pontiac Grand Am will be invaluable. It will show you diagrams of the hood latch mechanism and provide step-by-step instructions for accessing it.
* Professional Help: If you are uncomfortable performing these steps, or if you're unable to open the hood, it's best to seek professional help from a mechanic. They have the tools and experience to safely open the hood without causing damage.
Remember to be extremely cautious and patient. Force can cause more damage. If you're not comfortable working on your car, it's always best to call a professional.
