How do I fix "check engine light" for my 2003 Saab arc 9-3 Turbo
You don't fix the light, the light goes on due to any 100 of things associated with your car. You scan the car using an OBDii code scanner to pull a code out of the cars computer. Any local auto parts shop can do it for you for free, or have your mechanic look at it. You can post the 4 digit code back here and we can try to help further. Once the problem is repaired, the light will go out.
