    How do you know the low side is at 65 ?
    Have you checked your air filter?
    Is your air handler blower motor running?
    Are your evaporator coils frozen over?
    Is the condensor fan motor running when the compressor is running?

    What about the pressure on the high side?
    Do you have the correct level of freon in the system?

    Turn off, melt ice, turn back on, measure temp of suction line at condenser
