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

SOURCE: rear speakers stopped working

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 you need to take at least one side off. What I mean is the part when your sitting in the back seat the plastic piece were the armrest is. After you take at least one or both of these out just fold the seats down and the rear window carpet piece will have four plastic push pins then just pull it straight back and its out. After the carpet is out just unclip the speaker and pop it out then unplug the harness.

The front first you need to take the screw out of the small piece up by the side mirror and pull that piece out, then pull the metal clips for the window cranks, if you have manual windows. then the screws in the grab handles, the rest is just plastic clips. Just either get a specialty tool for this or I use a butter knife and slowly pry the door panel up and work it around the entir panel until its loose. sometimes no matter how hard you try to be carefull the clips will break though. They are failry cheap if they do and autozone should have them. after the panel is off it is pretty simple just take out the screws holding the speaker and pop it out then unplug the harness.

try different speaker if works .its the speaker. if another speaker does the same .your radio is the problem.

I have an 05 Cobalt that just experienced the same problem. I had my door panels off and my speakers appear to be dead.

If you have a multimeter, you can pull the speaker out and test to see if you get resistance across the two terminals. It should say on the speaker what the resistance should be (most likely 4 ohms). If you get no reading, you most likely will have to replace the speaker.

You could also test for AC voltage on the speaker wires. When the stereo is on, and set to a reasonably loud value, you should get a few volts. If you don't get any reading at the door, it may be either the wiring or the stereo. To determine which it is, you will have to take readings at the stereo output.

Hope this helps.

then it might be the motor to that window or a bad switch for that window.
