AC blows cold air but not enough air

i assume it has a working high speed?? if so it has to be a door not working correctly

i assume it has a working high speed?- nope, same model other cars works fine Checked the door no trouble wid tht either

Just had a.c. fixed.Replaced a air communicator. Now the a.c. isn't blowing any air.But the a.c. pipe is cold.

Ac system works perfectly but no cold air is coming to the cabin
