Turn on you ignition without starting the engine. Press on the gas pedal 3 times, all the way down. NOT TOO FAST OR TOO SLOW. The light should then go off.

From the 2002 Trailblazer owner's manual:

If your Trailblazer/Envoy is equipped with the Driver Information Center at the bottom of the instrument cluster:

1) Change your oil filter and oil.

2) Turn on your ignition without starting the engine.

3) Navigate to the oil life 0% display using the fuel info button (gas pump icon).

4) Push / hold the select button (arrow icon) until it resets back to oil life 100% (+/-10 seconds)

5) Take a test drive and drop off your used oil at a recycling station...

There is a reset button in the fuse box under the hood on the drivers side. Open fuse box and look for the "reset" button. Turn ignition switch on, hold button in for approx. 10 seconds. If change oil light reset was successful, the oil change light will blink for a few seconds.
