If the refrigerant levels are low or borderline the AC compressor will cycle on and off. Before taking it in for service just check a few basic things: check blower motor operation (low to high) - turn temp. selection to HEAT and fan to HIGH, do you get a strong air flow? If not blower motor may not be working (could be a fuse). Here are other suggestions: http://www.wikihow.com/Diagnose-a-Non-Working-Air-Conditioning-in-a-Car
