Question about 2003 GMC Sierra 1500

Open Question

Speakers in my 2003 sierra 1500 not working

There was a clipping sound in the speakers everytime i started it...now the speakers carry no sound at all..i cant even turn the radio on. It looks as tho the cd changer is still on showing 6 cd's.

Where is the fuse box...and would this be a radio fuse or speaker fuse....or a short?

first what you want to do is locate the water pump. then release then tension off the belt that it is connected to. there should be 2 or 3 bolts and undo them and pull it out. then replace with the new one.

SOURCE: No sound comming from the left side speakers in my 04 Envoy XUV.

first> road vibrations can cause cable connections to come loose so you can start by taking out your radio and making sure all of the questions in the back are connected as they should be.
Second> if this doesnt seem to work then the next step is to check the wires going to the speakers that arnt working (this will b quite a job, but if you can do it, it will save u quite a bit of money) .. checking the wires your checking for >bad connection to the speakers >cuts in the wire or if any part of the wire is touchin any other metal object

not sure which radio you have but there is an amplifier under the back seat and there are some fuses there you may want to check your owners manual for fuse information

2007 cierra ,my radio cones on but not putting power to speakers except to 1 front speaker and it has almost no sound ,up full and very screechy . do I need a new radio ?


Sounds like a wire is shorting out, probably in behind the stereo, but more likely in the back where the speakers connect. Check for something shorting out or a wire grounding out near the speaker.
You can trace back from there.
Other than that probably is the stereo.

2008 gmc sierra speaker


I have a 2008 Silverado and noticed my chime was not working. They work off the front door speakers. Found out GM put the cheapest speakers on the market in them. Bought a new pair of Kenwood speakers from Crutchfield and installed them last week. They sound great. I will probably install Kenwood's in the rear doors since it's only a matter of time before they die too.

I have a 07 GMC Seiarra Classic. The radio has some lights that come on or go off intermittently and the sound comes of and on on some of the speakers. I dont think it is a problem with the speakers...


I have the same problem. Seems when it is dry outside, the radio works pretty good but when the humidity is up, speakers dont work and sounds like treble in the other speakers.
I am to the point as to put a aftermaket radio in the truck.

MY FACTORY RADIO VOLUME PROBS


More than likely with a 2003, the speakers that cut out are in the door or doors. Do they cut out of both speakers?

If they cut out of one, then you may have an intermittent speaker ( the wire to the cone becomes partially connected)

If both speakers turn off at the same time and you hear NOTHING on all speakers, then you more than likely have an intermittent connection on the radio itself and probably replacement is probably cheaper than fixing the radio.

One more thing
Factory radios sometimes have an amplifier in them. Sounds funny but they call the Radio in the dash the Head Unit and the amplifier is buried in the dash. You could have a bad amplifier or a loose power connection to it, but that is very unlikely.

Hope this helps.
