your engine fan is not pulling airflow over your condenser at idle or their may be a condenser fan not working check for airflow issue at idle that is the cause of your problem make sure condenser and radiator clean. Many auto cooling/heating systems use a "blend door" which mixes both hot and cold air to provide air at the temperature selected with the temperature control. When the temp control is in the full cold position, the blend door moves to a position which allows only cold air to pass into the cabin/passenger compartment. That blend door is generally operated with engine primary [unmodified intake manifold pressure] vacuum. IF there is a leak in the primary vacuum line system, then at low engine RPM the leak may bleed off the vacuum necessary to hold the door in the cooling position. Then when driving, the vacuum will be much higher, "over riding" the leak, and allow the vacuum motor, which operates the blend door, to hold the door in the proper position and provide only cold air to the cabin/passenger compartment.
