The power antenna on my 2005 Sonata GLS is stuck in a halfway extended position. Turning the radio on/off does not result in any movement or sound from the motor that extends/retracts the antenna. My first thought was to check connections etc. I looked at hmaservice.com, but I could not find diagrams. I would appreciate some pointers as to where to look because the car is parked outside and it is too cold for me to enjoy trying to figure out where to look by guessing alone ;-) Thanks. Sinan
