Have the computer scanned with an OBD2 scan tool. Some auto parts stores will do this for free.
How do I reset the service engine light on a 2003 Chevy Trailblazer?
There is a green "POWER" light that comes on this 2004 Chevy Tracker. The light simi circular in the lower right corner of dash. There is no mention of any kind of power light in the owners mannual. The local chevy service dept. has no idea?? Can you help me?
If the service engine soon light is flashing on the 1997 Geo Tracker, you might have a sensor that has been activated because your vehicle is due to be serviced. You could also have a sensor that is malfunctioning.
Maybe you should service the engine soon. :P
can you tell me why my 1999-2000 Chevy trailblazer light is on
Check
there is no service engine soon reset switch. The vehicle is telling you is has a serious problem. the only way to check it out is to take it to a shop or get an OBDII scaner there is a reason for the light coming on. There is a failure within the controls of your motor. But to clear it you can disconnect the battery for five minutes.
When service engine light is on on a 2003 Chevy Trailblazer, the problem could be a faulty thermostat, a circuit range performance problem, or any other problem.

what's the question
That requires an OBDII engine scanner.
The check engine light (service engine soon) comes on and stays on when a problem is detected by the self diagnosis system of your vehicle.
