QuestionQUESTION: when the key is turned the stereo turns on and it plays an AM channel. when trying to change it to FM that button doesn't work along with any of the memory buttons or CD TAPE nothing i cant even eject the cd thats in it. so far the only things that work are the equalizer power putton volume and the speaker adjustment nob.
ANSWER: Hi Mike,
I believe this is internal to the audio console itself, unrelated to the car's wiring system. I checked the manual to see if there might be such an explanation. So removal of the radio from the dash and looking for blown electrolytic capacitors on the power board of the unit would be the solution. Gently remove the surrounding bezel will reveal the screws that hold the unit into the dash.

QUESTION: Thanks for the quick response roland i didnt think it would be so fast. i got the radio out and set infront of me where should i go from here?
AnswerHi Mike,
I would take a look at the circuit board(s) on which all the components are mounted and look specifically at the cylindrically-shaped ones (typically black colored) to see if any of them show sign of fluid leaking out on to the surface of the board where they are mounted or on the other side of the board directly underneath them. That would be a sign that they have 'opened' and need to be replaced by means of a soldering pencil to r & r them. The parts of the board that have any transformers or larger electrolytics are probably where there is a failure that would produce the sort of problem that you have. These are likely to be nearer to where the plug socket(s) are located.
Also check the connections between the control panel components and the circuit board to see if any wires from the control switched appear to be loosely connected at either (what we call a 'cold solder joint' and if so then touch those up with a soldering pencil. Just go over all the detail components to see if any of them looked burned, etc. Maybe you will spot a failed electrolytic which when replaced will restore a voltage that is needed to change the things that aren't working. If any of the controls have been noisy, another thing to try is spray those switches with electronic circuit board cleaner available in a spray can from an electronics store.
