SOURCE: 2005 Chevy Cobalt, how do you reset a fault code?

Your car has a OBD2 hook up under the dash somewhere on the drivers side, You have to have a computer to hook up to that ODB plug and reset it, If you live near a Autozone they will clear the code for you for free, One other thing you try is disconnecting your battery for about 30 mins, that works on alot cars to reset the check light.

SOURCE: trying to locate fuel filter on 06 chevy cobalt

Hello kino26763: You can locate the fuel filter at the rear of the car. You will need to raise the car so you can get under it. Be sure to use safety stands for your protection. The filter will be just in front of the rear axle. Passenger side at the gas tank. Should be a small round cylinder looking can.There should be three fuel lines coming off of the filter.

SOURCE: 06 Chevy Cobalt power steering msg and check engine light on

So I fell victim just as everyone else has. I hit 45,000 miles and my power steering went out and it cost $900 to fix it.

In order to get Chevy to recall this problem we all need to call the National Highway Traffic Safety Administration at 888-327-4236 or visit http://www.SaferCar.gov It will only take a few minutes.

I made a video and put it on youtube to help build awareness on the subject:
