CD player not working
Well, if you push the cd button and no cd player is installed, then you can try a salvage yard to find one and have an auto electric shop install it for you.
Otherwise, you can go to a place like Best Buy, and have them install a cd changer, like a Sony, for instance, that plays through a certain FM stereo frequency on your radio and they might be able to make it so that it powers up when you hit the cd button, although
many times they'll just have it power up on your ignition key being on, and you have to remember what frequency or preset on your radio to have to hear the cd-player play.
That's tech for you.
