Tom is correct check you stratification wheel and make sure it is on the blue dots. If thats ok and your a/c system is full of freon then you should check you water valve. This vehicle does not use a mixer flap in the air box to control the temperature it uses a water valve on the driver side near the air box, If that valve is stuck open then you will have heat coming in the passenger compartment even when the a/c is on. Hope this helps.
