However, there's no guarantee it's *exactly* in that location without consulting your owner's manual or a repair manual specific to your year and model. Some variations exist depending on trim level. The owner's manual is the best place to start. If you don't have it, you can often find a PDF online by searching for "2000 Oldsmobile Alero owner's manual".
If you can't find it using these methods, searching online forums dedicated to Oldsmobile Aleros might yield additional tips from other owners who have located theirs. Remember to be careful when working under the dashboard to avoid damaging wires or other components.
