New to the forum but have had a Verona since 2007, 145,000 on it. I recently replaced the Ac compressor and other Ac parts, works great, radiator and all other cooling system parts, alternator and belts and tensioner. Car ran perfect for two weeks, still runs good. All of a sudden all the lights are blinking slightly, alt checks out and I can’t find any loose grounds, anyone had this problem?
