Chevrolet Repair: Saturn L300 service light w/wrench, 2001 saturn l300, saturn l300

Question
There wasnt a Saturn expert, but saturn is made by Chevy so I thought you might know. I have a 2001 Saturn L300 and the Service light with the wrench has been on for a few months now. About 2 months ago I took it to a shop and had it diagnosed and they said that nothing showed up on the computer. Then about 2 weeks ago my service engine soon light came on so I went to Auto Zone and used their diagnositc computer there and it read P0050 which was a heater circuit. I took it to a shop and got that replaced, hoping my service w/wrench light would also turn off, but it didn't. Only the SES light went off. They also diagnosed my car to try to find a code for the SE light, but none came up. Is there a way to manually reset the light? Or do I have to take it to a dealership? I'm starting to think that the light is malfunctioning and there really isn't anything wrong... please help! We even unplugged the battery for 15 minutes to see if that would help, but it came right back on when I started the vehicle.

Answer
well that is very specific, and can see your talking to pple. talk to dealership right away. they will be able to see if anything wrong, or be able to properly troubleshot it.
plus they made the car, and have a vast list of issues and fixes..
i doubt the bulb is bad or malfunctioning, it came on for a reason.
had a newer car that the check engine light would come on for an oil change, ugh. replace oil and no more light.  could be something simple.. or complicated.. i hate idiot lights, they just say something up, look for it...
