Did you check the fuses I mentioned to see if they have power to them? (If a fuse or relay is bad the A/C nor A/C controls will have power to them.)
Remember, the easiest way to check the A/C CLU RELAY 51 is to switch it with an identical one. (There likely is and identical one, in one of the underhood fuse boxes) If after the relay is switched the blower and A/C works them the relay is faulty and needs to be replaced.
If the fuses and relays check out OK, check for power at the RED wire of the blower motor with the ignition switch ON and the blower speed setting on HIGH.
If power is present, the blower motor is likely bad or the connection at the blower motor is bad. (Wiggle the connector to check for a bad connection).
Let me know how these checks go, then if needed I'll tell you what to check on the HVAC control unit.
