To turn off overdrive in a 2003 Pontiac Grand Am, locate the gear selector on the center console. There should be an "OD" (overdrive) button or a switch on the gear shift. Press this button to deactivate overdrive, which will typically illuminate a light on the dashboard to indicate that overdrive is off. Remember to switch it back on for normal driving conditions when you no longer need it.
If your light switch is broken, you should first turn off the power to that switch at the circuit breaker. Then, you can either replace the switch yourself if you are comfortable with electrical work, or call a professional electrician to fix it for you. It's important to address a broken light switch promptly for safety reasons.

Because you turn on the light
The OD light on dash stands for Overdrive. There is a button (usually) on the end of the turn signal lever. Some cars the button or switch is on the dash. If you push the button/switch the light will change to OD or OD on (may even go out) then you will be in overdrive. Being in overdrive is good except for steep hills or pulling a heavy load.
