I had some electical problems with my 2005 cobalt as well. The headlights would not turn OFF - even when the car was off. It caused the battery to run down, etc. I took it to the dealer and they replaced the entire fuse block. The dealer said that this was the first time he had seen this problem & the first time he had to replace a fuse block. But he said it was not that difficult to do.
 
They also replaced the shifter - i was also having problems with the key getting stuck in the ingition. The guy at the dealership said that almost every colbalt that he has seen has had trouble with the shifter - they were cheeply made. But he replaced it and it seems to be working well now.

Electrical issues, Stalling by jrector74

I have a 2005 cobalt ls and it stalls out. The car simply shuts off while driving. It will start again when put into neutral. It is completely random. There are no specific conditions causing the car to stall. I took it to the dealership twice to have a diagnostic check. No trouble reports came back. Also, my cd player will lock and read error at times. The dealership as well as GM have been very cooperative, but have not satisfied me with my situation. They have both told me there is nothing they can do for me. Since it has been a recurring issue, at least once a month for over a year, I think I may persue a lemmon law issue. Has anyone else had this problem?

I have 600 miles on my new 2007 LT, I love it.
I can see the low fule message on the display, if I ask for it. I looked though the manual but see no other dash warning of low fuel. can I add one. Will it flash on the display if it gets lower?

2007 Cobalt aftermarket Amp by roguewatchmen

I'm pretty new to all this, but I bought a sub and amp for my new Cobalt. We grounded it to the wiper fuse origionally, but that didnt kill the amp when the car was turned off, so they grounded it to the reverse lights, this worked and I went on my way. A few days later I went to clean my windows while driving and it seems that grounding it to the reverse lights disables my wipers all together. I pulled both of the wiper fuses and both were in working order, a friend of mine said he could hear the relay clicking like it was trying to work. Anyone have any idea's on this? If I disable my amp then it works fine, I'm guessing that its drawing to many amps throguht he electrical system, the wipers have a kill switch for when they have to heavy of a load on them like snow, so maybe its causeing that to kick into effect. Anyone know where I should groud this at?

Only one with Elecitrical issues???? by ryanm1

My girlfriend has a 2005 Cobalt that she bought used so it has no warranty. She just started having the issue with the key being stuck in the ignition due to the shifter button not releasing fully. Does anyone know if the microswitch pin is very complicated to replace yourself? The dealership wanted a little under 300 bucks to fix it there. Does anyone know where I can get instructions on how to fix this issue or close to it? I can't even find a way to get the shift knob off without taking apart the whole center consule. I would purchase a haynes or chiltons repair manual for the car but no one seems to carry one in this state. Any help would be much appreciated, we are getting tired of leaving the key sitting in the ignition over every day. Thanks.

The Cobalt has a 3 year/60 000km warranty that is fully transferable to the new owner so the car should still be covered under warrant if it's under. I would talk to GM consumer affairs to see if this is the case in the U.S as well. As far as the Chilton and Haynes manuals go there is unfortunately no manual for this car as of yet. I have a 2005 Cobalt LS as well and the only option is the GM service manual (about 150$ but worth the investment).

I suspect that they have exceeded the warranty mileage. In the US the warranty for 2005 Cobalts was 3-year 36,000 bumper to bumper, 5-year 60,000 powertrain. Now for 2007 it is 5-year 100,000 powertrain, but I believe still 3-36,000 bumper to bumper.
