There are literally dozens of possible scenarios that can cause this. First start with the basic visual inspection of the intake and hoses for vacuum leaks. Also remove the belt and turn the compressor by hand, it should turn relatively easy when rotating the center part of the pulley, if it is as hard as opening a Gatorade bottle, then the compressor is bad. Also verify that the voltage does not drop excessively when the compressor kicks on, lower than 10 volts will indicate a voltage issue which could be anything from a weak battery to a weak ground.
