2000 Oldsmobile Alero 30 amp ignition fuse blows

30 amp ignition maxi fuse (batt 2) fuse under hood blows when a/c is turned on, causing the vehicle not to start. After troubleshooting the problem, I found if I unplug the A/C compressor, the fuse does not blow, leading me to think the compressor clutch was shorting out. I replaced the compressor with one from a junk yard, only to have it blow again, wasting my time and money. I have no wiring diagram to go by, and I can't figure out why it blows only the ignition/batt 2 fuse and not any other fuses in the a/c or heater circuit. Any and all information is greatly appreciated, thanks

Yes, it is very strange, which is why I'm having a hard time trying to figure this problem out, especially since I haven't got a schematic yet. I'm not sure what amp fuse is #37, I'm not with the car right now, but I'm pretty sure all of the fuses are the correct amperage, I will double check though. Is there anything else you want me to check when I get to the car?
