Question about 2002 Chevrolet TrailBlazer

Rear speakers stopped working

The rear speakers on my 2002 Trailblazer are not working. The fronts are fine, but I am getting nothing out of the rear.

How do I get access to the back of the stereo system to check the connections?

    Rear speakers do not work at all, and the front speakers will get quieter when breaks are applied.

    Rear speakers failed to work for a while. just recently they can be heard faintly. Front speakers seem fine.

    My rear speakers just stopped working in my 2002 Trailblazer just after my kids were using the headphone jacks on the rear unit. Does anyone else with the rear speaker problem have the rear radio unit? I wonder if this is part of the problem, I know these radios are actually tied to the cars computer, GM's genius idea??? Anybody found a solution? The following site shows how to remove the radio: http://forums.trailvoy.com/showthread.ph...

My speakers went out front and rear i was told by an audio tech. that the systems that chevrolet put in them each speaker has its own amp to bust the sound the only way to fix it is to replace them.
if you have a warranty chevrolet will replace them otherwise find a junk yard or new system. i ordered a set of used speakers off ebay havent installed yet.

The rear speakers stopped working in 2006 Tralblazer


The most common solution is both rear speakers are bad. Not what you expect, but is what we usually find. could be a driver in the radio.
Go back to the rear speaker and put your ear right on the speaker and notice if there is a faint sound.
Have a test speaker and plug up before you buy the correct ones.

Rain got into my truck window now my speakers has stopped working...what should i do?


Could have damaged the speakers or the radio or both.
You could pull a door panel and connect a small used speaker to see if the radio is producing a feed to the door.

My 2002 Chev Trailblazer, the 2 rear speakers are not working. I know they are linked to the rear seat stereo and when this is on it is supposed to shut down the rear speakers but the rear seat stereo is...


Sounds to me as if you may have a short in the speaker wires or they may not be hooked up at all. follow from back of stereo follow wires all the way to rear speakers making sure that they are not showing any bare spots.
