hey guys I have a '93 sedandeville and had a question about the radio and wasn't exactly sure where to ask.

I bought the car used, and the radio has never worked. It looks like someone has replaced the antenna in the past as there was an extra one in the trunk. I was wondering what all I could do to try to troubleshoot / fix it and get it to work.

It has the normal am/fm stereo + cassette player....

Does it power up? Does the light come on? Does any part of the unit work? Have you checked the fuse?
