When its around freezing temp outside the FM stations on the radio wont work the stations come in real fuzzy. Once the car is been running for a wile “stop and go” the stations then go back to normal. Its a 2000 Chevy cobalt coupe. Do you guys have any idea of what it could be, I thought since theres a couple guys with cobalts on here, Maby you can help
