radio doesn't work

the fm radio on my car just wouldn’t work, even after i installed a new deck, im sure the antenna cable is plugged in, but the actual antenna wouldn’t go up. I was told that the antenna was just for the am radio, but will that affect the fm radio also?, or is there another source for the problem?

It should work regardless of AM or FM. Make sure the antenna wire is hooked up to the deck so that when the head unit turns on, it turns on the antenna as well (so that the motor winds the antenna up and down). Should be blue with white stripe wire I think, if I remember correctly.
