My radio want come on, it just come's on when I push the eject button.

The radio needs replaced.

Do you have a CD in the radio unit that is stuck? That sometimes happens. If not, there is s sticky sensor switch in the radio. Depending on the cost of the radio and or replacement, it may be less expensive to replace it. Go to tadio shack or a car radio repair place if you can find such ... and ask if there is any way to cheaply fix the radio. I have a CD stuck in my radio that is in my BBQ and I can't figure how to get it ejected. Can't get to it with a hammer.
