I've got a 2004 Trailblazer and I've recently run into a problem with my radio. Here's the deal...

There is no sound when I have my radio set to an am/fm station. However, I can play CD's without a problem. Any thoughts as to why the radio does not work, but the cd player will? Thanks in advance - SD

I think since you can play CDs and listen to them without problems, your unitoutput is fine, you have to check your receiver circuit, look for a connectionthat is not fixed. Otherwise, take your car to repair shop but don't let them convence you to replace the whole unit ;)...

the labor on troubleshooting might be more than the radio's value. FM sucks anyway. cut into your AUX wire and put an AUX port in. buy a mp3 and plug in your own songs. that money is a physical gain....troubleshooting is money out the door.
