Ac clutch doesn't turn over. Ac blowing hot air, freon charged ok, 2 fuses ok, what else would cause this problem? There is a diode. Blower and controls all working, everything seems to be working ok. Any help would be greatly appreciated.

If the Freon charged ok the clutch had to be working if it's not now it probably all leaked out. Have it leak checked first then performance tested.

The clutch had to work to charge it unless a charging station was used. Was it leak checked then? Try jumping the pressure switch on the accumulator that is the big silver thing on firewall there shold be twowires there. If the clutch works then there is a leak, if the car cools then the switch is bad. Also check fuse and relay underhood.
