2007 Cobalt electrical issue-Help!

Hi everyone. I'm new to forums and this is my first post. Last week I bought my fiance' a 2007 Cobalt LS 2 door 5 speed with 43k miles. It is a pretty basic model which has no power window/locks. The second day we had it while I was out, I noticed that the drivers door speaker stopped working. I thought that for some reason that speaker just died. As I approched a stop light I put on the turn signal. The light in the dash flashed accordingly as did the outside indicators, but the little "tick tock" or "ding" type noise that tells you your blinker is on also had stopped working.

Later that evening while on a seperate trip, the drivers speaker started playing again AND the turn signal sound came back to life. They are somehow definately related as the same problem happens basically on a daily basis now. If one is out, them they both are out...if one is working then they both are working. I've looked thru the book at the fuse box and under hood fuses but don't really see where they would run off the same fuse, etc. I'm at a loss as the rear drivers or other front speaker never goes out. Thinking possibly a ground issue somewhere (???) but have no idea even where to begin to look. Any help would be greatly appreciated. The dealership I bought it from was no help as they were only willing to honor the power train warranty, and wouldn't even take a look at it without charging me. Thanks in advance!-Matt

I think the turn signal sound come through that speaker.

You've been turned away by the dealership correct? I would suggest that you speak with our Customer Assistance Center at 1-800-222-1020. They will be able to speak with the dealership you are working with to see if they can't cover you to get the problem fixed. I hope that helps.

Customer assistance was really no help. They contacted the dealership, but the dealership was unwilling to waive the diagnostic fees, so I guess I'm back at square one

Hi 07cobalt,

Welcome to the Chevy Forums.

I would recommend you level the playing field by assuring your battery connections and grounds are solid first. It's inexpensive, and could save you some time.

Replace the battery terminal bolts. Verify the battery cables are clean and dry, and not starting to corrode. Hows the engine -to- firewall ground strap? A #4guage negative cable from any bolt on the engine to any clean ground on the firewall will act as an acceptable ground strap if your ground strap is getting dirty, and hard to reach. When the grounds and negative wire start to lose clean contact, they can sometimes selectively deny power to certain individual circuits. Needless to say, it will only get worse with time.
