Got the truck back shop where flushed radiator, vacuum lines to hubs replaced, along with vacuum pump. At first the air would blow cold out of defrost vents now it won't blow cold. I've replaced the hvac heating vent a/c switch, and the auto locking hub vacuum and control valve solenoid. And I tried to recharge it but it won't accept anymore Freon. Any ideas on what it could be? Its 110 outside and I need A/C soon.

check for a vacuum leak at hvac start at motor and work your way back good possibility one of the hvac vacuum lines were left off so none of your vacuum motors in heater will work. or if yo have a water shut off valve that may be not working either.
