AIR COND NOT COLD AT TRAFFIC JAM

2003 Mercedes Benz C180

Air Conditioning problem
2003 Mercedes Benz C180 4 cyl Front Wheel Drive Automatic 50000 miles

My car is a Mercedes Benz c180k. When I come to a traffic jam, the car air cond becomes a blower and the cool air stops to come out. For short distance travel, when I come to a traffic light, it will slowly become not cool. I need to move the gear to free gear instead of drive gear, the air cond becomes cooler. This is cos the tetrometer has moved from 600 to 750 rpm on free gear.
When I travel high speed long distance, and when I come to a traffic jam, the air cond become a blower again no cooll air. Need to switch off the engine and then switch it on again. After awhile, the air cond is back to normal with cold air flowing. Do not know what's the problem.
