Radio Stopped working

Grim_Smoker · #1 02-13-2004, 07:17 PM

So I jump in the truck today with the g/f to go look at some furniture stores....no music playing even though its on track 7. Change tracks, no sound, not even little buzz/whisper you get when you turn speakers up loud with nothing playing. Change cd's...nothing....radio....nothing. Nothing nothing nothing. Stupid fracking radio, anyone else had this problem? I'm gonna call the dealer and talk. I'm not going to pay those suckers to fix it if I'm just going to have a system put in. So anyways, anyone experience this? Radio says its playing the CD/radio station, but not a sound...

Cool, thanks Klaus. The tech at the dealer said they've run into this before, usually a blown amp.

It's happened to me before, just had to turn the radio off then back on again.

Happened to me once before,I shut the truck off then restarted and all was fine. Never happened again.

Hummer Man · #7 02-14-2004, 11:19 AM

Disconnect battery and turn ignition key to acessory and the back to off. Remove key, reconnect battery. You should be fine!
