The low pressure cutout, a compressor protection device, probably has the unit not operating the clutch on the compressor. Low pressure is usually due to low freon. Did you hear the click today when you first started the car and turned the A/C on? (Subsquent attempts to turn the A/C on and hear the click are not what I am asking about.)
