Is this the stock changer? Or was it aftermarket?
If it's aftermarket, you will have have it serviced at a local electronics place. Factory, pretty much the same thing, but you will have to bring it into the dealer and have them send it off to an Authorized Delco/Stock repair center.
This is extreamly common!
I have been working in audio electronic repair for 5 years now, and have personally done hundreds of these changers.
