Hey everyone, My father in law has a 1999 Olds Cutlass with the 3.1 V6 that he's been letting me drive for a while and recently its been suffering from some intermittent electrical problems. They started when suddenly all of his instrument panel warning lights ceased to work, except for the service engine and airbag lights. Then the brake lights went out, and finally it started cutting off on him. The interior and exterior lights flicker then the engine will die. But, when you come back to the car after its been off for a few hours/a day, it will fire right up and run a while then do the same thing. He's convinced it needs a new alternator, I'm thinking a bad ground, etc. What do you guys think? Thanks!
