Ac Problems

The air blows but no cold air and I dont hear any pumps kicking in or any load on the motor can anyone help please im stumped

Make sure the system is fully presurized, the system has a low pressure cutoff and if there is not enough gas in the system the compressor will not cut on. Other than that check the relay on top of the compressor to make sure it is activating the clutch when you turn the AC on.
