If you're experiencing an electrical problem, your best bet is to:
1. Check the fuse box(es): The Grand Prix likely has at least one under the hood and one inside the cabin (usually under the dashboard). Consult your owner's manual for the fuse box diagrams. Look for blown fuses (a broken filament inside the fuse).
2. Check the Power Distribution Center (PDC): This is a more advanced fuse box, often located under the hood, and may contain larger fuses or circuit breakers. Again, your owner's manual will have diagrams.
3. Have a professional diagnose the issue: If you can't find a blown fuse and the problem persists, take your Grand Prix to a qualified mechanic or auto electrician. They have the tools and expertise to diagnose the electrical fault. Trying to troubleshoot this yourself without proper knowledge can be dangerous and potentially damage the vehicle's electrical system further.
Trying to locate a "fuse-able link" without the correct diagrams and understanding of automotive electrical systems is unlikely to be successful and could be dangerous.
