go to autozone and see why its on, they check it free. One word of caution however, they will give you the code, they do not diagnose the problem. They may guess and suggest a part(as they sell parts)based on the code description, but this is still a shot in the dark.
I had a light on and I went to Advance Autoparts and the counter guy printed out a history of codes, all of which came back that my O2 sensor on the tailpipe was faulty. When I changed the sensor, I had to diconnect the battery to reset the warning light. You have to leave it disconnected about 1/2 hour to reset.
Before going to Autozone and checking codes, try the "reset" button located in the fuse box (open driver's door and look on the side of the dash). Key in the "on" position, engine not running, hold the reset button until you hear the chime ring a couple of times. Once the light is reset, if it comes back on within several miles of driving I would definitely have it checked out.
turn off engine, and start again

Have vehicle scanned to determine the problem and have codes cleared

The service engine soon light on the car dashboard to alert the driver to a problem with the car. A specialized computer scanner or code reader can diagnose the issue.
Depending on the year it may look like a little yellow engine, or it will say check engine, or service engine soon.
On a 2003 Oldsmobile Alero, the fog light fuse is located inside the dashboard fuse box on the right. The fog light fuse is a ten amp fuse.
