I have a 2004 Tahoe with a CD/tape/radio. First the CD would not eject. It would still play but not eject. It makes an ejection type sound but it never comes out. Now it has stopped playing. I have tried new fuses, unhooking the battery, manually getting it with a knife. None of those worked. Would appreciate any tips on how to get the CD out and fix the problem, if it's possible.
