It's the " service engine soon " light to the left of the gas gauge instead of the " check engine " light , like it is on my 1995 Ford Explorer
Use a diagnsotic code scanner to find out why the light is on, repair the problem and if the light doesn't go out after the problem is solved, it should after the engine has been started about 3 times.
If the problem has been corrected, you can clear the codes by disconnecting the ground cable from your battery for at least 10 seconds. After being repaired. if your Blazer has the OBDII system it needs to be cleared with the scan tool. The procedure above works for the OBDI system.
