* Under the hood in the fuse box: This is the most common location. The fuse box is usually located near the battery. The relay itself might be labeled, or you'll need to consult your owner's manual or a wiring diagram to identify it. Look for a diagram on the inside of the fuse box cover itself.
* Under the dashboard: Less common, but possible. This would be in a fuse block or relay center usually located under the steering column or on the driver's side. Again, your owner's manual is crucial here.
To find the exact location:
1. Consult your owner's manual: This is the best resource. It will have a diagram showing the location of all fuses and relays.
2. Check online resources: Websites like GM-Trucks.com, repair manuals websites, or forums dedicated to Buick Park Avenues may have information about the relay's location specific to your trim level. Searching for "1994 Buick Park Avenue fuel pump relay location" is a good starting point.
3. Look at the fuse box diagrams: Even without a manual, the inside cover of the underhood fuse box often has a diagram identifying the components.
Important Note: Before working on any electrical components, always disconnect the negative terminal of your car battery to prevent accidental short circuits.
