popping off?

compressor not cycling do you mean? if yes... the compressor will not cycle if the coolant is low or if there is no ground (the clutch is ground activated)

did a shop fill it or did you do it with the auto store cans? i see you mentioned vaccum so i am assuming that you had a shop draw the coolant out then refill it... should be 134a so check the pressure on the low side with a gauge if you have it. if the pressure is high and doesn't move the compressor is probably beat
