1998 pontiac gran am code help

Looks like power window codes. Remove the negative battery terminal. Put a test light between the cable and the negative battery post. If there is a draw like you say, the light will light up. Now find the fuse or circuit breaker for the power windows and remove it. I bet the light goes out. Then you will need to remove the door panels one at a time and unplug the motors one at a time to isolate it in the same way.
