I just got my 04 F250 Diesel back from the dealer after shelling out $5100 for head gaskets. The dealer also replaced the batteries while it was there. Now my CD player won't work. I called the dealer and he said it's nothing that they did and I'd have to bring it in. Does anybody know if this is an easy fix problem? Is the radio tied into the engine management like on a VW that could have been messed up when they did my gaskets? It was working fine BEFORE I took it to the dealer. It has 6 CDs in it but says NO CD when I try to play them. When I try to LOAD it says CD ERROR and does nothing when I try to EJECT. WTF. I'd rather not spend more money on a new CD player. Any of you techs out there know something the dealer may have done that may have caused this. The head gaskets blew within about three months of getting the coolant system flushed on the truck. It's turning into a series of unfortunate (for me) and expensive coincidences with this dealer.

Try this...

When trying to eject a CD take a thin knife blade and see if you can lightly pull forward on the top of the CD to get it to eject.

I had a problem similar to your and once I got the first CD out, was able to eject and reload all 6 and it worked fine after that.

You should be able to see the front edge of the CD by looking in the slot, then slide the blade in on to of the cd, press lightly downward while slowly sliding the knife/cd out towards you.

Those 6 CD player are junk. Good news is you can take it apart and get your cd's back.

If you look closely at the unit when you take it apart. There maybe a little gear that has fell of the motor. If you push it back on it will most likely work again.
