    This is on my brother's 2000 Grand Am 3.4L.

    When he bought the car, the AC worked fine, two weeks ago it went out for no reason. I thought it was a fuse, and I replaced 3 different HVAC fuses (one on the passenger side interior and 2 under the hood). Nothing changed, so I figured it was the blower motor. While pulling appart the interior to replace the blower motor, I noticed ANOTHER fuse panel, this time on the passenger side interior. I pulled the cover off and found another HVAC fuse (20A). I pulled it and found it was blown. So, I replaced it with another 20A, and as soon as my brother turned the ignition to ON (didn't start the car) the replacement fuse blew. I didn't have another 20A, so I replaced it with a 30A. Turned that ignition to ON and that one popped too. I'm lost as to why this is happening. Stock is 20A, but it's not even lasting a second upon startup.

    What should I check next?

    You should pull the connector off the ac compressor and multimeter it to (ohm) ground. See if something is grounding it. Then find the relay and check that.
