Either you will pay a dealership or car mechanic to look up the code, have them fix your car, and have them clear the code or you can fix it yourself, and disconnect the ground on the battery for about a minute and hook it back up. Should clear the code.
Take it to auto zone and have the codes read for free.
If you mean service engine light, then take off the gas cap and put it back on correctly. The fuel system is pressurized, if the cap is not on tight the check engine light will come on. At least three clicks.
you can't reset it, fill your coolant up full, both rad and overflow. the light will go out. if it is still on when everything is full, then your coolant sensor is broken or unplugged. if you light goes off then comes on again and your coolant is low, then you have a leak. if you have a 3400 engine in your lumina common leaks are intake gaskets, waterpumps, and head gaskets.
with a timing light, assuming this is an older engine that still uses a distributor.
the light is a warning to you that something is wrong and your engine is not operating correctly and needs to be serviced soon. Most times there is a part of the emissions systems that set it off, like a bad sensor somewhere. You will need to get the CODES read. The codes are then converted to a diagnostic problem and then the parts of that system need to be analyzed to see which one is not operating. I will ask this....did you just recently get gas? You must turn the gas 3 clicks when you put it back on to make sure the correct pressure is in the gas tank otherwise you will get a check engine light. So go check your gas cap and if it is tight.........then you will need to take your car to a place liek Autozone and they will put a diagnostic scan tool on your car usually under the dash under the steering column and pull your codes. From there it is up to you where you decide to get it fixed, either by yourself or a garage. By the way after you tighten the gas cap you will need to drive some miles AND go thru a few stop and start cycles with the engine befoer the service engine light goes out if it was a gas cap issue. The light will not automatically turn off after you tighten the cap.
How do I reset the service engine light on a 2003 Chevy Trailblazer?
There is no reset, the there is a problem with something the computer is coding for a reason. If you are thinking it is an "idiot" light there is no such thing. Have the engine trouble tested at your local auto parts this can usually determine the problem.
i unhooked the battery...(both terminals)
Maybe you should service the engine soon. :P

Your check engine light should come on. You will have poor performance from the engine, no get up and go.
It is quite easy to install the 1992 Chevy Lumina brake light switch. The brake light switch simply plugs in and out.
If you live near a vocational school or career center, you might check their Automotive department. They might be able to help you out for a donation to the class.
