if the rear is cooling than the freon level is fine...... do not add freon!!!!!!
It is probably the temperature door under the dash.
Does yours have the manual knobs or electronic?

The low pressure a/c port is on the accumulator, which is below the starter solenoid and behind the 2 main enigne connectors on the passenger side.

The door is internal to the assembly under the dash but the actuator that moves the door is external to it somewhere. Do you feel any difference running the heat up front or is it the same temperature? The door is what makes the vent temperature change. It changes the flow of air between the AC core and Heater core or a mix of both.
