Not that I can diagnose your air conditioning fault by e-mail, but it has been my experience that the majority of problems like you describe are because of low Freon, and not because of an electrical fault -- unless a fuse is blown, and you already checked that. Neither the fan nor the compressor clutch would engage if you are low on Freon. You didn't say what model year you have, but a set of R-12 gages is about $30 and R-134 is about $70 (the major difference between the two are the connections to the system). Getting gages to do your testing will probably give you a much quicker answer than finding and testing all of the electrical connections for the A/C system.
