Since the last time I changed the oil in my 'O3 TrailBlazer, which I have done many times, the "Change Engine Oil" light stays on for a full 20 seconds each time I start. I have tried to reset it, as per the owner's manual, but it continues to stay on for the full 20 seconds. Any ideas?

I've got the same issue and don't know why it's doing it. I've changed it about 6-8 times now without an issue until this one. Any one have any ideas?

Why Worry about 20 Seconds, Worry if it will Not go Off.

We have a 2002 Trailblazer and the change oil light will not turn off! We have tried exactly like the manual says but it does not work!

To get the "change oil" light to turn off, you turn the ignition to the on position (the position right before you start the engine), and mash the gas pedal three times. The engine should not be running during the process. The next time you start your SUV, the "change oil" light will come on with the rest of the dummie lights and go off with them as well. This is the process that I use on my 2003 trailblazer and have also read that it works on 2002 and 2004 and can only assume that GM most likely kept it for the rest of the year models. Hope this helps everyone out.

That is so awesome, we had the same problem with the oil light and it has been on for about a month. It worked for our 2006 Trailblazer

The last time I changed the oil in my 2004 trailblazer I used the same method that Donald has advised and it worked.
This oil change I tried the exact same thing and it's not working. I guess I'll keep trying.

Sometimes it takes more than one try. The pedal needs to go completely to the floor and then be completly released each time. You only have a second or two to get the sequence done.

I was just about to take my 2006 Trailblazer into the shop (again) because of this issue. It has been on for about two weeks so i figured i would try this and it didn't work the first time but i didn't go completely to the floor. So, i did it a second time and worked like a Charm. Thanks everyone, this saved me a bunch of time!!

THANK YOU VERY MUCH!! I called the dealer because I wanted to see if there was a way to do this without taking it in and they basically told me the same thing but left off the part about not starting your car. They told me to start the car and do everything else this said to do and it didn't work and I was just about to take it in and did a GOOGLE search to see if anyone else could relate and got this thread. I did this to a "T" and it worked. THANKS AGAIN!! Just make sure if you are doing it to let the pedal come back up again each time after mashing it down to the floor. IT was the second try it worked for me.

I complete oil changes regularly (every 5000 km) on my '04 TB however recently my oil service light has been coming on after I start the engine. It remains on for a short period of time then it turns off. Is this perhaps a precautionary warning of a due oil change?
