Signal light flasher on a 1991 Pontiac Bonneville SSE?

The signal light flasher on a 1991 Pontiac Bonneville SSE is typically located under the dashboard, near the steering column. It's often a small, square or rectangular component in a fuse block or a dedicated flasher unit. However, there isn't one universally agreed upon location, and some models might have slightly different placements.

To locate it:

1. Consult your owner's manual: This is the best place to start. The manual should have a fuse box diagram showing the location of the flasher.

2. Look in the fuse box under the dashboard: Many vehicles place the flasher relay within a fuse box. Often, it's a removable component that might be labelled. Look for a fuse block that is accessible from under the dashboard, usually near the steering column.

3. Check behind the glove compartment: Some vehicles might locate the flasher relay in the space behind the glove compartment.

4. Look near the steering column: If you're unable to locate it in the fuse boxes, check along the sides or behind the steering column where wires and electrical components are bundled.

Important Note: Before working on any electrical components, disconnect the negative battery terminal to prevent accidental shorts or damage to the vehicle's electrical system. If you're not comfortable working with automotive electrical systems, it's best to consult a qualified mechanic.
