We most likely have a freon related issue, but we need to start with checking the pressure in the system to find out if when the compressor comes on the pressure is correct.

However, we also need to make sure the compressor actually comes on.

If the compressor is not kicking on the we need to jump power to it and find out if the compressor will come on and blow cold air.

If not, then we have a failed compressor. If it does, then we need to dig into the control side as this could be a relay or even a pressure sensor issue.

So, let's start with this info and go from there.
