When your service light is on, what do you do ? maybe the method you can try first when you faced this situation. Try alternatives first if buying a scanner is not an option. On some makes and models, disconnecting the positive battery terminal for several minutes causes a computer reset, and the erroe code will clear.

The car is old, if you want to add air conditioning on it, it will cost you much more money, I think you can sell it and buy a new one that with a/c.
