AC Blowing Hot
 

Hey all,

I have a 2005 C55 AMG, and it has been blowing hot air for a couple months now.

I am just now getting around to fixing it now since it has been livable up until now with the Arizona heat coming on.

Tried a new compressor and expansion valves, and neither did a thing.

Did an AC service as well. Still nothing.

If i park in the shade overnight it will blow cold for a bit when i first start driving and then get hot within 30 or so minutes

Any help would be apprecaited

The car does not have any self diagnostics therefore your FUYAA will not solve the problem---get a set of gages on the car----what are the H and L readings at various engine revs
