Question about 2004 GMC Envoy
No i dont think your alternator is going out but you can test it easily there at home simply by taking the pos battery cable loose while the vehicle is running...if it continues to run it means he alt is good if it dies then you wil need a new alternator.its a sure fire way to know if its good or bad.
