2008 Mazdaspeed 3 AC Compressor Replacement

AC in the wife's 2008 Mazdaspeed 3 quit working on a road-trip in New Mexico with temps approaching 100 degrees. Getting it repaired on the road would have been between $1000-$2000 dollars with labor and OEM parts. She toughed it out and waited till she got back home and I fixed it for under $400 including buying some new tools (gauges).
The video shows some basic AC troubleshooting techniques like checking the pressure, fuses and relays.
Then we R&R the AC Compressor and accumulator and vacuum and recharge the AC system.
