A buzzing alternator on a 1997 Chevy Express 1500 5.7 could indicate a few potential issues. It may be due to worn bearings, which can create noise as they fail, or it could be caused by electrical issues like a faulty voltage regulator or poor connections. Additionally, if the alternator is overloaded or failing, it may produce a buzzing sound as it struggles to maintain output. It's advisable to have it inspected to prevent further damage.
