Replace the engine the engine locked up and I need to replace it.

The auto locks on my 2005 cobalt work, but when I unlock the car, the alarm goes crazy. This happens whenever I use them, which is very rarely. The guy who sold it to me said not to use the auto locks. So if you guys know what to do, let me know.

The heater blew the BCM fuse. Replaced fuse and unplugged resistor. Heater works on high. Car travelled over 200 miles that day with the heater on high. Next morning the heater did not work. Could it be the heater fan? No noise came from the heater fan.

Been trying to do this for a week

I just got my ignition switch fixed and I was wondering if that had anything to do with the recall for the ignition switch?

When you start the car its not too bad.but when it warms up it hits hard

My car dashboard first begins flashing and the power steering warning comes up. The car then begins jerking and I lose the power steering. The odometer then begins moving up and dropping back down. The car also turns off a few times when I press brakes when this is happening. My car is automatic however when the gears sounds like it is having difficulty shifting and gives a very hard jerk when it does shift. This happens frequently and lasts for a very long time sometimes weeks on end. Many people have had this same complaint online but no one actually states if they ever got this issue resolved.

My a/c started to blow hot or room temp air. Took it to the shop they filled the gas and still . Next put on the computer showing ambience temperature sensor . It got change . Still the compressor doesn't start . They said that it run enough charge of electricity for the compressor to start but it doesn't . Finally told me I need to replace the compressor. Is that an accurate diagnostic and how much would be an estimate to fix it?

It will sounds like it doesn't want to start but will for now and this is every time i start the car for a couple of days

The alarm light will come on when starting the engine (not all the time). Car is garaged and not locked. I can still drive the vehicle but the transmission shifts hard and irregularly. Engine does not stall. Restarting the engine sometime fixes the issue but rarely. After driving a short distance, turning off the engine and let stand for 20-30 minutes, restarting resolves this issue. The ignition cylinder has been replaced by GM recall.

The other day I replaced a head lamp in my cobalt, I must have left the lights on and the battery died. Got battery charged and then engine light came on. The car won't shift out of first gear when driving. I hear a clicking sound that sounds like its coming from the shifter area when I apply the brake. It's an auto transmission. Can anyone help me please?

Just fixed my drum brakes and replaced my sparkplugs and coil pack along with ignition control module the other day. I don't know what the problem could be. It just started to jerk. Could it be moisture or my transmission or the transmission fluid?

Have there been any recalls issued

Only makes noise when going over gravel or bumps and when declining in speed

parking brake cable has a spring an a retainer on what kind tool I would need to compress the spring on the cable

trac light is on,abs light is on, check engine light is on, a car with a lock on it shows on, and when driving my car jerks and all the lights will flicker on and off and when i lock my doors then try to unlock the alarm constantly goes off and sometimes car wont start and when all lights are on i cant see how much gas i have or the speed im going or anything and when i put car in drive the doors dont lock automatically

I HAD A FULL TUNE UP TODAY ON 1/9/15. I had ( ALL 4 SPARK PLUGS AND SPARK PLUG WIRES REPLACED, COMPLETE OIL CHANGE, TIRE ROTATION, AIR FILTER AND CABIN AIR FILTER REPLACED TODAY ).

Now when I gave my Mechanic my car there was very low fuel in the car. ABOUT ( 38 MILES OF FUEL LEFT IN MY TANK ) when I gave my mechanic my car to do this service work.

Now I put ( CHEVRON TECHRON ) in my fuel tank with hardly any fuel left in my car.

RIGHT AFTER I PUT THE CHEVRON TECHRON FUEL INJECTOR CLEANER IN MY " CHECK ENGINE LIGHT IMMEDIATLEY CAME ON" ).

I went right to the gas station and put 1/2 a tank of fuel in my car.

Now I know it's not anything my mechanic did wrong. I know it's from putting the FUEL INJECTOR CLEANER IN MY TANK WITH HARDLY ANY GAS IN THE TANK WHICH IMMEDIATELY CAUSED MY CHECK ENGINE LIGHT TO COME ON ).

I have a ( OB2 SCANNER ) .

I scanned my car.

( 2 CODES CAME UP )

Codes were---- ( PO 171 )
It said ( BANK 1 SYSTEM TO LEAN ( HISTORY OF MILAGE)

NOW IS THIS FROM PUTTING THE FUEL INJECTOR CLEANER IN MY GAS TANK WITH HARDLY ANY GAS LEFT IN THE TANK CAUSE BANK 1 TO RUN TO LEAN? because I know it can be the O2 SENSOR. IT HAS TO DO WITH THE ( AIR/FUEL RATIO ).


CODE 2---- ( PO 455 )

It said---- ( EVAPORATIVE SYSTEM )
( LEAK DETECTED )
( GROSS LEAK/ NO FLOW )
( INTEMITTED )

So I know that code ( PO 171 ) BANK SYSTEM 1 to lean should have been putting the fuel injector cleaner in when I shouldn't have . Because the check engine light came on IMMEDIATLEY after I put in the fuel injector in with hardly any gas in the tank and as soon as I started the car the check engine light immediatley came on after I did this. ( OTHER WISE ) please tell me if I am wrong and give me or try to give me a more accurate answer to this, but I know it's the ( air/fuel ratio ) with no gas in the car air probably built up in my fuel system then by adding the injector cleaner made it run way to lean. Does that sound accurate and correct?

Now with code ( PO 455 )
This has nothing to do with code ( PO 171 ) correct?
This is something entirely different. So there has to be a leak in my EVAP SYSTEM SOME WHERE RIGHT?

What does ( GROSS LEAK/ NO FLOW / INTEMITTED ) mean???

PLEASE E-MAIL ME BACK AS SOON AS POSSIBLE PLEASE AT ( DM1341916&GMAIL.COM ).

I will be bring my car back to my mechanic on MONDAY 1/12/15 to have him go over these codes and to check these problems.
But I always like to get a second answer/Opinion from an Expert also.

Please contact me back at the E-Mail address I provided as soon as possible.

Thank you very much,

diag. said change maf map fuel fiter only after changing fuel filter did the car ran again for 30 miles then started to bog down engine lite flashing help

Not hot enought, just luke warm heat

So, my Chevy cobalt climate control panel wont switch the direction of air flow. The A/C works fine and so does the speed.
Actually the heat gets little hotter then it should I think. So I bought a new one and it worked great right away from the start... for a day. Then it switched the flow on the face and wouldn't switch back to any other direction. It sucks because the part is pretty expensive, and I would really like to figure this out.

Key currently in ignition and won't come out or even turn to off position
