you could have a vacuum leak at the blend door actuator also check your freon level

is the cold air coming out of the defrost vents?
ANSWER by , July 30, 2013
this car has several different valves that control the a/c and heater. a dealer can run diag on your a/c to see if it is more than just a Freon concern. did one not to long ago, heater valve stuck open. no cold air. set a code in the control module.
