#11 of 107 Fuel low Light by rlenker Jul 07, 2007 (9:23 am)
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?
#13 of 107 2007 Cobalt aftermarket Amp by roguewatchmen Jul 07, 2007 (11:40 pm)
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? Replies to this message: poncho167 (Jul 08, 2007 5:40 am) mike13083 (Aug 04, 2008 11:25 pm)

#15 of 107 Only one with Elecitrical issues???? by ryanm1 Jul 17, 2007 (10:01 am)
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.

Replying to: ryanm1 (Jul 17, 2007 10:01 am) 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). Replies to this message: poncho167 (Aug 13, 2007 4:42 am)

Replying to: cav_rider666 (Aug 12, 2007 11:54 am) 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.

#20 of 107 cobalt:power door locks and security system by aase1991 Oct 28, 2007 (6:12 pm)
I have a 2005 cobalt. The power door locks inside the car stopped working, but the remote door lock will lock the doors but won't unlock them. Also the security system activates whe I open any door to get in(lights flashing, horn blowing, etc). The security system problem didn't start until the power door locks quit working which makes me believe that the two issues ar related. I checked the fuse for the door locks and it appeared fine. I also disconnected the battery to try to reset the ECM. Any suggestions? Replies to this message: scottevil0106 (Dec 05, 2007 12:17 am)
