I found the problem with the fan today. There was an intermitent loose wire feeding the fan switch that was not giving enough current to run the fan and turn on the a/c compressor. Just rewired the hot wire coming to the switch vs removing the whole harness to try and find the place where the wire was bad. Cold air again!
