Question about 2004 Chevrolet TrailBlazer
My SES light came on yesterday under what I would consider to be normal driving with no noticeable problems (at least to my untrained eye and ear)... I ran the OnStar diagnostics, and they told me they received signals indicating an error with ether transmission or power train.
Today, I called the Chevy dealer, and they want $100 just to run a diagnostics on it. Then the repair costs would depend on what they find.
Is there anything I can do prior to bringing it to the dealer to check things out on my own?
1. Turn key to the "on" position but don't start car
2. Pull the PCM BAT and PCM IGN fuses in engine compartment
3. Wait approximately 5 minutes
4. Turn ignition off
5. Replace fuses
6. Start the car and the make sure the light has went off.
then check to see if your gas cap is on right. If this light comes on again then it is time for the dealer. If you can't find them fuses then just disconnect the battery for five minutes reconnect the battery and when you start the truck the light should be out. just let it idle for 2 minutes with no heater or radio on. and you set. I hope this helps you.

The Service Engine Soon Light has been mostly on lately, although it periodically goes off. Since we had a remote starter installed, we have had problems with the battery and the 04 Trailblazer sometimes needs a jump. Today, we had the back latch open and sure enough the vehicle needed a jump. The good news is ..the ses service engine soon light went out after that event. The advice to pull the fuses or disconnect the battery seems to have some merit Thank you ! I just hope it stays out !!
