Check the high and low pressures-if okay could be the air blend door not fully opening if okay have the HVAC control module tested.

Checking the high and low pressures tells you about the amount of freon in your system, the air blend door could be stuck half way between heat and cold position and being mixed together, that's why its not that cold
