My single CD unit will not accept or reject discs. Once opened, I see the transport gears moving but evidently gear does not rotate the rubber roller. Will attempt to find if gear has separated from roller shaft or if other plastic drive parts have become loose or broken. If final drive gear can be glued back to rubber roller, then I may have success. I am not sure if any TIMING MARKS are to keep gears / shaft synchronized. Have any others seen this issue ?

Anyone know where to get a parts diagram of the internals of this CD player? I had mine appart and cleaned it, finally got everything where its supposed to be but it will pull a cd in and just buzz. The gears ⚙️ wont shift to either eject or play. It was working. I think I lost a part that shifts the gears. Just need an image to verify if I lost something.

I have a GM radio just like this. It works but only has sound when it seems to warm up and the temperature is above about 88 degrees in the car, I have to turn the dash heat on for about 5-10 minutes then audio pops on and works fine until you turn it off again. Then repeat to get sound. I'm decent with board soldiering and i have re-flowed as many connections as I could inside but it did not fix the problem. Any ideas what inside the unit causes this?

I got the cd out but it will not accept or pull a cd in. Is there a fix for that?

I am trying to get a shop to fix mine. I think they need to install new parts or check whats going on internally

Mine's stuck in the "just ejected a CD mode" and locked there after pushing out the last cd. Can't push another cd in because slot blocked by internal mechanism

I have the gm nav radio in my 2013 Suburban. When I try to insert a cd, I feel tremendous resistance, like its being squeezed from the sides. When I first acquired this vehicle, I pulled three broken cd from the slot using needlenose pliers. Now nothing loads.
