...now it wont go out?What ? I got stuck in a snowbank, and got a bunch of snow stuck up under the car, but that was the night before. Its driving perfectly, not overheating or nothing, How do you reset the car computer, disconect the battery? Or what should I do?

obd2 cant reset by disconnecting battery anyone that works on cars knows that i would check the wiring to computer cause it sits in right front fender well and gm had recall for wires rotting and track light coming on

Many parts stores keep an OBD2 code reader to pull codes for customers. Disconnecting the battery for a few minutes will reset the computer. If the light comes back on find a code reader and pull the codes to see what it is and work from there. The first thing I thought of is perhaps when you hit the snow bank it disconnected a sensor. O2 sensors are down low and that would cause a check engine light. That's just a theory.
If you do reset the computer and the light never comes back then I wouldn't worry about it at all.
