Question about 1998 Chevrolet Blazer

2 Answers

Have a 1997 Chevy Blazer. The last year the radio has been cutting out speakers. First it was the right channel. Now left rear is gone. Someone suggested it was the radio unit itself, but I'm thinking wiring. Any ideas on how to diagnose?

It's the radio it self, The radio has 4 separate channels for the speaker's. It's common for the amp to each speaker to fail one at a time, I had the same problem and picked up a OEM radio at the Salvage yard for under $75.00. Just make sure your have the radio code before you pull one from the yard and if you don't you can talk them down for less and you can get the code to the radio at www.radio-code.com. I did that but try 0000 for a code if the radio calls for one. I had the same problem and picked up a radio at the salvage yard and had mine repaired and it's still sitting in the closet for 8 years now. Good luck and hope this helps.

You might have faulty wiring or just a bad connection. I would check the connections to the speakers. You might need some in line fuses as well.
