Where is the fusible link in a 1991 Pontiac Sunbird 4-cylinder?

The fusible link in a 1991 Pontiac Sunbird 4-cylinder is typically located in the main fuse box, often under the hood. However, there's no single definitive answer without consulting your vehicle's wiring diagram. The location can vary slightly depending on the specific trim level and options.

To find it:

1. Consult your owner's manual: This is the best place to start. It should have a diagram of the fuse box showing the location of all fuses and fusible links.

2. Locate the main fuse box: This is usually under the hood, often near the battery.

3. Examine the fuse box: Fusible links often look different from regular fuses. They might be larger, have a different color, or be labeled differently. They might be integrated into the fuse box itself, rather than individual components.

4. Look for heavy gauge wires: Fusible links are usually on heavier gauge wires that supply high current circuits, such as the starter or ignition.

If you can't locate it in the under-hood fuse box, there might be a secondary fuse block located elsewhere, but that's less common in this model year. Again, the wiring diagram is crucial.

If you're unsure, it's best to consult a qualified mechanic to avoid damaging your vehicle's electrical system. Incorrectly replacing a fusible link can lead to further problems.
