AC Blowing warm air
I have a 2016 GL 450. The AC started blowing warm air. The AC compressor belt and center are spinning. I connected a AC Pro can to see if its low in freon, it didnt show the pressure, the needle pointed to red which indicated see instructions, which says its something else. Looking for tips to troubleshoot to identify what is wrong before I replace the compressor?

Are you sure you connected the gauge to the correct port? If it's on the correct port I guess it must be showing that the compressor isn't compressing. The green and yellow ranges are for when the compressor is doing its job, and pulling the low side down.
