Do the vents change? If they don't maybe you have a vacuum leak somewhre.. not sure if its a flapper from hot to cold or not.. but if it is a vacuum leak would keep the flapper from moving to change it. also have you turned the ac on and checked inside the cab against the firewall to see if its cold?

Did you just charge the system, if so how much did you put in? Too much or too little will cause warm air to blow out.
Is the compressor engaging normally? Is there frost/condensation on high psi line between condenser and evaporator? It would also be real helpful if you rented a nice ac gauge set and got the high and low side readings.

Enough with the multiple threads on the same topic please bud. You need the right equipment to work on an AC system. The Haynes AC manual will give you info on most of these questions and will let you know the hazards of working on an AC system. I suggest you get it. You can be seriously hurt.
