You're the one looking at the car. It's rather difficult to diagnose it over a computer. You have to make the observations. You have to do the troubleshooting. You have to provide the symptoms.
Does the compressor turn on and run steadily? Is the condenser getting hot? Air there vapor bubbles in the sight glass? Does the fan blow air? Is the air coming from the correct outlets? We can't tell any of those things over a computer.
