Please don’t mess with that switch. It is controlled by a computer somewhere in the car. There is a detailed troubleshooting process in the FSM on the a/c system.
Let’s start here!
Does the light on the switch turn on when pushed? The fan has to be on for that button to light up. I have low pressure not engage the clutch and I have also had a bad clutch coil cause a problem. This year I had to replace my compressor, the system was charged and the clutch engaged just no flow from the compressor.
