where do I find my codes?

If you are looking for the RPO codes that is the sticker inside the glove compartment. If looking for build date and misc info that is a sticker on the frame rail driectly under the drivers door. If looking for OBD engine/drivetrain/brake system etc codes that is same as always plug in to the system with a OBD code reader. I hope that helps.
