Stereo Speakers Go Off on 2008 Chevrolet Avalanche

My stereo speakers are going on and off depending on the weather. When it's rainy, wet or cold, only one of my speakers works. When it dries up and it's sunny or warm all the speakers gradually come back on one by one. Started at around 25K miles.

Sounds like wet speaker connections. Get to the speakers and look for corrosion or wetness and address it. If you can't find the trouble, go to an auto electric shop. I'm assuming you have the original sound system. If you have aftermarket, maybe you need to go to where you got it installed and have them look at it.

Having the same problem. 3 speakers work now instead of 6...then on any ocasion they pop on...sometimes 1 or 2 or 3 more speakers...trying to find out where connections are. This has been going on after 50K miles...
