Question about 2007 Chevrolet Cobalt Coupe

1 Answer

I have a Chevrolet Cobalt 2007, I recently changed the battery Dec. 8 and it was fine. New Years Eve, I went to the store and when I came out it was dead. The lights would turn on and so would my ac, but my windows wont go up or down, the doors wont lock and my radio is dead as well. I would like to know if you can guide me through this issue. Thanks

It sounds like the alternator is weak or has gone bad, if you can jump start it take it to your local auto parts store and have them test alt/charging system. Lights & fans don't draw that much power but windows and locks require more. Sounds like you've been running on battery power from 12/8

Misfiring car

try doing a tune up.. plugs wires and fuel filter.wouldnt hurt to dump in a bottle of fuel injector cleaner either. usually that clears it up if not have your ignition control module and coils tested (most parts stores do this free.. atleast in ny anyway) if they come back fine i would start looking at your fuel pressure and fuel pump but with it being an 07 i doubt you will have to go that far...if you didnt have a tune up done before this post who knows after 3 years they could still have factory plugs and wireson it. My old landlord went a few years without having a tune up done on her car.

i can only go by what your saying here, but to me it sounds like its your starter, either selanoid or drive, either case its best to replace it. can you find anyone around with some mecanical ability like a local michanic or auto parts store that can look at it for you. if i was there(witch i'am not) most likely i could tell you what is wrong.
