Low refrigerant. Buy a can of the 134a with a sealant in it so if you have a small leak the system may seal with out replacing any parts for a while. if the AC compressor cycles on and off continuously you need another can of 134a. Make the second can one with a tracer dye...not more sealant. That way if the system does leak more the leak can be found.

AC fault. Hopefully just low on refrigerant gas which is simple to re-gas. Could have a serious leak though so that needs more money to fix. A competent shop will be able to hook up a combined re gas and leak check machine to test it.

It could be a lack of freon caused by a leak in the system.
