Air Conditioning Died--Suggestions?

[dudefish]

My air conditioning suddenly stopped working a couple days ago. I did not notice any unusual issues before it quit. It was cooling well, and then all of a sudden stopped blowing cold. No noises or anything. The compressor does not even try to engage. Any ideas on things I could try to troubleshoot before taking in to the dealer? I've checked the fuse and it's OK. There is an A/C relay in the under hood box, but I haven't been able to test it because I don't know the pinout. Any suggestions? This Alabama heat is BRUTAL!!!

Either the LO or HI pressure switch are preventing the system to come ON
Locate them, disconnect and jump them to confirm

Check your compressor clutch, mine just quit. Basically melted the rubber on the clutch itself, and so far I haven't found a replacement without buying the entire compressor.
