In my 2008 Cobalt, the front speaker in the driver door went inoperative - no turn signal noise, no warning chimes for door open with key in, seatbelt chime, low fuel chime, and of course, no music. All of those sounds come through the speaker. I switched the driver door speaker and the passenger door speaker, and now I have all of those noises back.

If you have manual roll down windows, you'll have to buy a special tool to remove a little clip that's behind the roller handle. This tool was included in a kit for about $7 that I bought at Harbor Frieght, but you might be able to find the kit at other auto parts stores. Google "removing window crank" and you should be able to locate a video that shows how to get it off.

Anyway, I switched the speakers and now we just don't have music coming out of the passenger door speaker, but at least we have all of the warning chimes and turn signal clicking noise again.

The dealer wanted almost $200 for a new speaker and to replace it (labor). Rediculous.

5W30. but make sure it meets GM spec. GM6094M I would use Mobil1 or other synthetic that meets that spec.

check the fuse panel for the emergency flashes and pull the fuse,, It probably runs more than just that one function, but at least you'll save the battery untill you get a new switch
