2000 s40..... antenna goes all the way up but then I hear the motor still clicking. I only hear it when I start the car and it only lasts for 30 seconds but I'm afraid it will burn up the antenna motor. I started the car with the radio off and heard nothing and then turned it on and after the antenna when up I could hear the sound behind the driver's side back seat. Minor..I know..... I love this car!!! Any thought?
