2006 chevy trailblazer_ls
Like most post i've seen my radio is doing the same thing, working in the warm weather and only the tweeters in colder weather. I was checking all my grounds and open the fuse box cover under the driver side back seat and saw that theres a black delphi box on the fuse block. It has a what i would call a color grid one side says tan one says grey but the indicator says blue, does this have anything to do with the radio? MY door and fuel chimes are not working. I hate to buy a new radio to fine out it maybe somethin else. (i do not have the boss system) any help would be greatly apperciated.
