2010 ml350
ac no cool
Hello everyone!
I have a 2010 ml350. the ac worked great last year but hasn't cooled at all this summer. Im familiar with this type work, but it seems I may have a clutches model as the center of the clutch hub never stops rotating. is there a way to tell and what could be the problem? older clutched systems when the clutch pulls in iff the compressor is ok and you have refrigerant and air flow you have cooling, Im not up to par on the workings of this type design. can anyone explain it to me or point me in the right direction?
Thanks
Charles

I haven't looked into the HVAC system but this 'might' have a variable displacement compressor??
Owning HVAC gauges are cheap and there are plenty of internet resources for simple diagnosis on the HVAC.

Check your AC Clutch;
My problem was that when I bought the car, the air conditioner worked at first, then stopped working when the car accelerated. (No fault code, new freon)
then the clutch of the air conditioner compressor broke, its parts flew away and it did not cool at all.
I bought a new clutch kit and now it always cools. https://www.autodoc.co.uk/nrf/12875379
edit:
My problem persists. The car cools well when it first starts, but after a while the air conditioner starts to stop working.
