My speedometer was stopped working, It was reading 40 mph when I was going around 65. Than it dropped to 0.
After I turned off ignition everything now works.

This is a fairly common problem, Gm has actually issued a service bulletin regarding this repair. The problem probably originates from one of your wheel speed sensors that is mounted inside one of your front wheel bearings. To be sure, you need to have the car scanned to find out which one and then you have to replace the whole bearing assembly because the sensor is integral to the bearing. The bearing is not hard to do but you will need some professional tools if you want to do it yourself. At a shop it should cost between 3 and 400 dollars complete.
