The ac compressor wont come on it is full of freon and the fuses are good and the relays are good too. I can get it to come on if I put ground to the a/c relay. All the fuses and relays are good the a/c system is new the only way I can get the compressor to come on is to put a ground to the relay in the juction box

The computer might not be grounding the AC relay or a problem with the pressure switch and also still low in freon-Check it with a manifold gauge
