My car ac works but it doesn't blow cold air. on 2000 Ford Taurus

well the ac blows and the pressure is good and everthing but no cold air. i took it in for a free ac check and they said everything was fine but they need to do a full ac diagnostic to find the problems. anybody have any idea what could be the problem?

It sounds like the blend door actuator. The blend door determines the amount of cold/hot air delivered to the cabin.
