AC systems will sometimes quick cycle if there is a clogged or faulty expansion valve or switch . I haven't paid that much attention to the AC system operation on this car ,but heres some basics . If the system does have a partial clog the system triple pressure switches see the high pressure build as the compressor runs and shuts off the ac clutch prematurely and doesn't cool efficiently. The liquid tank (accumilator) may be partially clogged also . A certified AC shop or good dealership guy should be able to tell you what the issue is. Sometimes these syptoms come from a compressor going bad and metal debris getting distributed thoughout the AC system. The low side will have extra low pressure when looking at a gauge set and the high side will register high enough to possibly look somewhat normal because excess pressure is blown off from a relief valve on Nissan systems .
