CD Changer not working :(

[twizller]

My 2002 grand prix se never came with a cd changer so i went on ebay and i purchased a cd changer that works with all gm models with the pre-trunk harness (which i didnt have). I went to buy the harness (#12344015) and installed and plugged everything in. Now when i try to play the cd, it says E33 on the radio (its the cassette radio without the cd player). I checked the wiring and everything seems to be fine.

Anyone know what is wrong with it and how to fix it?

first things first. Does your radio have changer controls? does it have a cd button on it. Even though they say the changer will work with "all" gm radio's doesn't mean it does. I would check the model # on your radio and your changer and go to a dealership to find out if they're compatable. Secondly, how do you know that the changer worked before you got it. You're just relying on somebody else's word.If possible, I would try you're changer in somebody elses gm vehicle that has either changer controls or a factory changer already installed, and see if it works. If you stilll get an error , chances are the changer's bad.

I go with dopey here. E33 means a tape or CD loading problem. The issue here is if the radio knows how to talk to the changer. Installing a phone line between a German and Spanish does not mean they can talk at all. Check the radio model to see if it supports a Changer

I hve checked if the radio is compatible with a cd changer and it is. I asked on clubgp and they said it is, and it also has the input for the wiring harness (#12344015). I talked to the ebay seller and he said he will offer a full refund, as i think it is the cd changer. And also, none of my friends have a GM vehicle with the stock radio in it

Thanks for the help
