Good morning, the vehicle compressor is not functioning and the light on the A/C button is blinking. There is refrigerant in the system. What could be the cause of the light blinking?
Could I have circuit diagram for this?

First thing you need to check is the 15A heater fuse located under the left driver side. If the fuse is good then try swapping out/replacing the MGT relay located in the engine compartment fuse box.

If all those checks does not resolve the issue then check for battery voltage at the black wire with yellow stripe at the compressor. If you have power then your compressor could be the defective part. I would also recommend you scan your vehicle for codes. If there is an issue, the engine control module will store a code. Keep us posted on those checks and if you need further assistance.
