service engine light wont shut off

You need to go to a store like auto zone who would read the codes for you if not you need to find someone who has a code reader.

Already got the codes and made the repairs. Just want to turn the light out

The light would automatically go out after about 30 minutes to 1 hour if problem was taken care of if not and you get the light turned off it will just come back on.

All stores that read codes do not turn them off so you would have to found someone that has a code reader like a friend and have them turn it off for you.
