* Under the Dash: This is a common location for many vehicles. Look behind the instrument panel, possibly near the steering column. You might need to remove some panels to access this area.
* Fuse Box: Some Buick models integrated the flasher relay into the fuse box itself, either as a separate component or integrated into the fuse box assembly. Check both the under-hood fuse box and any under-dash fuse boxes. The owner's manual *might* indicate if it's in a fuse box.
* Behind the Glove Box: Less common, but possible.
To find it: Your best bet is to consult a 1993 Buick Park Avenue repair manual or a wiring diagram. These will show you exactly where the flasher relay is located for your specific model. Online parts stores or repair manuals websites often offer these diagrams.
Without a diagram: The relay itself is usually a small square or rectangular component. It'll likely have multiple wires connected and might have markings that indicate its function. If you can trace the wires from the turn signal switch, you should be able to follow them to the relay. Be cautious working with electrical components and disconnect the battery negative terminal before starting any work.
