A/C won’t blow cold. It’s been charged, blew cold for bit but back to warm again. The control panel is not showing snowflake to show it’s on.

It sounds like you have a leak, once the system if full it works okay, but when the refrigerant leaks out it stops working. I would start the engine and turn the A/C on, then lift the hood and see if the A/C compressor clutch is turning (front) if not the system is low again. Here are two guides to help us see what's going on. Please go over them and get back to me so I can help you fix it.
